I'm talking new next-gen titles that people actually care about. 

The PS4-XB1 are going to have an overwhelmingly advantage. As in we're talking like both of their libraries will be well past several thousand games by then. 

You don't think the average consumer will notice that? 

How will the eShop guarantee that?

Wii U, 3DS, PS4, XBO and Vita all had their eShops, PSN and XBL ready at launch, neither of them launched with hundreds of games.

It's a hugely incorrect assumption to think that people won't care about those games. People don't buy PCs because of new games. They buy because of old games. You get steam because it's a legacy platform of old any new games that transend generations. The only reason consoles have had to depend only on new games to sell hardware is because there was no streamlined way to play older games at launch. That won't be an issue when the NX launches with a preliminary steam-like library of eshop games from the get go.

I think the average consumer hasn't bought the Wii U and will see most of those games as new games they don't have access to yet and will gladly jump on board because they aren't Wii U games anymore, they're simply eshop games. The line of thinking will be the same as buying into Steam after you made the jump to PC.

Because the eshop will be used on the NX whole sale and seamlessly, unlike the prior marketplaces. The NX will launch with the full Wii U, and likely select 3DS, library of eshop titles from the get go. It will carry over. PSN didn't have the PS3's library of digital games when it transitioned to the PS4. The NX will. And it won't be some half assed work around like Wii mode on the Wii U which didn't even have retail digital games at launch. It will be the full library accessible from the main NX eshop day one, from retail to indie. None of the other guys did that, and it would have been an absolute game changer for the one who did if they did.

So why not buy a Wii U? They apparently like the games so much but yet they don't want to play them for some reason. Doesn't it have thousands of Wii titles and an OK-ish selection of Virtual Console games too. 

Nobody but like 10 people bought a Wii because it played GameCube games. 

STEAM is not comparable to what Nintendo does or what you're describing. Just because you slap 10 year old games on a online only shop doesn't make you STEAM. 

STEAM just unifies the overall PC market, and the PC market is successful due to its flexibility that consoles don't offer ... I can upgrade my GPU whenever I want to have the highest end graphics. I don't need to wait another 3-4 years to play a game in 4K if I feel like it. Is Nintendo going to do that? Hey if Nintendo allows *that*, then that's a legit game changer, but I doubt it. 

What third party games are offered in this magical Nintendo backwards compatibility service? Is the last Grand Theft Auto there? Last year's Call of Duty? Things like Left 4 Dead? What if I feel like checking out the last Fallout or Bioshock game? Those on Nintendo's service? Witcher III looks cool but I skipped Witcher II maybe I should go back and play that. Can I? Nope, nope, nope, nope, and nope. Since Nintendo never got any of those titles, they won't be on this magic NX service, it'll mostly just be a back catalog of Nintendo games and their mediocre third party titles from the last 15 years. 

We don't know that. How can you be so sure of that? NX will probably be a different architecture than Wii U. Why should all Wii U games automatically run on NX? Do they emulate the PowerPC on hardware which ain't much faster (or probably even slower in case of the NX handheld) or will they add expensive hardware for BC? How big and heavy will the NX handheld be if it has to be able to play WiiU games (which were optimized for different hardware) additionally to native NX games?

I would be very happy if the NX hardware is 100% backwards compatible to Wii U and 3DS. But I have serious doubts that it will happen.

The horrible UI experience hide's that behind the terrible "Wii Mode" the NX won't have to deal with. :D And again, the Wii U had all it's other problems.

Gamecube BC on the wii when you buy an extra controller isn't comparable to an entire marketplace of immediately downloadable NES to Wii U games that will share the same market space as the newer NX games from day one.

The NX will have it's own flexibility thanks to more frequent hardware upgrades and it's hardware independant platform. The NX will "just" unify the overall NX hardware market. You know, like apple and it's line of highly successful devices.

They don't need to be there at launch. The hundreds of other games will suffice in the begining. Then they'll get the adequate amount of third party support post launch. Judging the Wii U, they'll likely get their fair share of late ports too down the line and even at launch. Only difference is that the NX won't be launching a year before the successors to its graphical competitors make its hardware obsolete. Not that that will be an issue for the NX as it would be able to match the competition within a year if such an unrealistic situation arose this time with a hardware upgrade, to no damage it the older models thanks to this scalable platform.

So they'll be as successful as STEAM without having any of the back library that makes STEAM successful in the first place because ... the user interface (which you are assuming based on nothing) is going to be so wicked amazing? You do realize too that companies like Microsoft and Apple actually invest *billions* of dollars in their OS right? Little Nintendo is going to show them up by investing a fraction of that?

That aside, actually if they want to do the STEAM route, then grow some balls Nintendo and do it. Do it full stop though. 

Make basically a "PC Box" just with your service (instead of Valve's) that has a PC CPU + GPU which can run all existing PC games. Then you easily throw a Wii U chip and voila -- now you have a singular device that can play virtually every PC game and every Nintendo console game ever made. 

Now you can start a shop on that hardware where developers can take their existing PC games (hundreds and thousands of them) and you can say to them "hey sell this through our store, if it sells through our eShop, we get a $5-$8 cut per download, you have no porting costs, so no downside for you."

THAT would be a legit game changer, because as a developer literally I don't even have to "port" my game to this system. It already works on it, so if some Nintendo fans want to buy it, hey, more sales for me even if its like only 10,000 extra sales. *That* I could see working and that would be a legitimately bold step. Unfortunately like I said, I don't think Nintendo would go there. Maybe they'd flirt with the idea, but then chicken out or get hamstrung by some ass backwards old timers on their board of directors that wouldn't like it because it's not Japanese enough of an idea. 

Handheld. 3DS has been out longer than the Wii U so I feel like it would be the first one I upgrade too.
However, if Nintendo engaged in some bundling goodness then I would jump on getting both at the same time (if the price is right of course).

We don't know a lot of things, but we can infer from Nintendo's comments about absorbing the Wii U's architecture to avoid software droughts when launching new platforms, on top of their recent comments on the importance of BC, as a pretty safe assumption.

I actually have doubts about how many Wii U games will be compatible on the first generation NXDS, though, simply because of the change in screen resolution. But the NX console is pretty much guaranteed to be 100% BC with the Wii U eshop. And I think it's 80% likely to have the same with the 3DS eshop. The caveats of that will be from all the duplicate games like Smash 3DS, VC, etc. Though I'm sure they will find simple way to just make those games unpurchasable on the NX platforms.
