If I were to translate the Wii U's performance into previous generation terms I would say that it would be like Nintendo releasing a system with a dual core processor running at 1.5GHz (Power PC 970 MP like the mac mini) with 128MB of memory and a GPU based on the Radeon X600. Inexpensive, low energy consumption, and low processing power compared to the competition, but based on more modern technology and more viable for cross platform development.

Had Nintendo done this and been as successful initially you (probably) would have seen many developers react differently; and I would expect many companies to have designed for the Wii and enhanced for the HD consoles, which could have helped the Wii to sell better and re-enforce this strategy.

Instead of porting ME3 or Batman, they needed to convince publishers to port new games like Watchdogs, Far Cry 3 or Remember Me. Why re-make Ninja Gaiden 3 when they can put resources to develop a version of RE6 or with EA for Medal of Honor?

I like the console, but don't see any reason for PS360 owners to go for a Wii U.

If the Wii U was comparable to the PS4/720 it'd have no problem running every game in its launch window at 1080p without even breaking a sweat. Assassin's Creed 3 and Madden NFL and Batman Arkham City shouldn't just be "maybe a little better", they should be easily better than the PS3/360 versions.

Wii U is marginally more powerful than a 360/PS3.

PS4/720 are going to be large leaps ahead of all of those platforms, Sony has said it themselves, there's no point in making a PS4 until it can be a very large leap above the PS3.

It doesn't really matter though, because third parties treat Nintendo like crap anyway. Nintendo doesn't just have an issue with hardware fidelity, they have a massive demographic problem. The kids who play Call of Duty/Assassin's Creed/Halo and all those types of games are all XBox/PS first type of gamers.

Just because Nintendo is now finally getting ports of franchises that have been on their PS3/360 for years now is not going to impress them. And then when 720/PS4 comes out, they're going to see games like Star Wars 1313 and Watchdogs, which are either not going to be on the Wii U period (as of now, it's a no) or are going to have to be scaled down to run on the Wii U, and really of that demographic, how many people do you think are going to buy the Wii U version?

The Wii U runs Assassin's Creed and Batman at 1080p; whether it's native or upscaled is beyond me. Ubisoft said they aren't spending much money on their Wii U games right now so Assn's Creed and their other launch title won't look that good. Like I've said on these forums several times, there won't be an insanely high jump unless Sony/MS wait until around 2015-2016 to launch at a decent price, and do you really think BOTH of them will wait that long?

As for the dempgraphic thing, you're pretty much right, but Nintendo hasn't shown us how they'll get the hardcore. At least give them an adequate chance to show us before the system launches. Games like Watchdogs and other multiplats would work just fine on the Wii U because the Wii U can run UE4 ie, they won't be scaled down. 

Unfortunately, AC3 and Batman are not confirmed to be 1080p yet.

I stated this earlier in the thread soemwhere but Nintendo's E3 and information strategy has not been aimed at PS3/X360 owners.  It's been aimed at Wii only gamers.   They've openly stated this.  They plan to start targeting X360/PS3 owners over the next few months.   Ever notice that Nintendo is forbidding all these big publishers and developers from speaking about their projects until Nintendo gives the OK?  This is why.  When they say "Go", the floodgates targeting PS3/X360 owners will open.  I suspect later this month will kick it off.   Right now, they are still concetrating on the launch of the 3DS XL and New Super Mario Bros 2 and the ability to download the full retail game on the eShop.

Oh, I see. Well, as a Wii owner they are doing a good job with the games, bad with the marketing (E3 presentation), but games are there. Wonder what kind of games they will show for PS360 owners.

I think COD, Ninja Gaiden, ME3, ZombiU and maybe RE6.

Agreed.  I think we'll see soem other big projects as well.  Capcom may have soemthign exclusive to show soon.  We'll also see a few more Western developers with Wii U projects.  Developers that largely ignored the Wii completely.
