This logic doesn't make sense. New games would require sufficient hardware power. If it does have enough power it will get many PS4 and XB1 games not all as its a handheld, but if it doesn't have enough power developers wouldn't be able to port their games.

As you said it will sell to existing Nintendo fans but there is less reason for anyone else to buy old games on it unless they want it on a portable. That's something I personally do want, but not Skyrim :P

That's exactly what I said to begin with.

As for mod support, I asked a rhetorical question and said "we'll have to wait and see."  

Portable hardware technology is not there yet to make Switch as powerful as a PS4 especially if its $500 or less. Its proably less than half the power of an XB1.

And who said , to get a third party developer and publisher it need to have a powerful GPU :) ?

The important word here is "probably". We don't know. The rumors (which were right about everything so far) talked about a console less powerful than an Xbox One, maybe even a lot less powerful.

What I'm really interested in is the power in handheld mode and the development needed for the home>handheld transition. If you need another version of your game for the handheld mode, it could really limit the 3rd party games. Because no, the handheld Switch won't have a PS4 power. It would already be great if it had a Wii U power. And no, "just a few effects less" is not enough to port a PS4 game on Wii U. It's easy to port handheld games on the Switch, but we lack information about the home console games ports on the Switch handheld. I wouldn't be surprised if some games were unplayable (officially or not... 10 fps games incoming?) in handheld mode.

It depends on whether it uses Tegra X1 or something better. If it uses Tegra X1 it will have 512 GFlops of power and will still be pretty expensive. As a portable it should have a 1080p screen at least and running modern games at 1080p on a console half as powerful as XB1 will be difficult with many effects turned off and no anti aliaing probably still wouldn't run them. And it would look bad if it doesn't have a 1080p screen which is standard for smartphones, some even have 2K and 4K screens.

And it definitely does not appeal to the same demographic as PS4 Pro. The hardware gap is be too big, PS4 Pro is going after a more premium market than PS4 and I would suppose Switch. But its a handheld so it could still appeal to people who want a PS4 and PS4 Pro but not in the same way.

PC isnt getting RDR2 either, lmao

Let's wait and see, it's normal that publisher support a new console at the beginning.
Only time will show if this continues over the years.
As of now I can imagine that Nintendo Switch will end up in the same situation as Wii U (no third-party support, only first party-party support) but let's hope that this won't be the case.

The same thing happened with GTA V but PC got it later not Wii U.

That's what some people said when we asked the same type of questions about the Wii U, the Xbox One launch or the Steam machines. We still have no real information about the Switch, just the concept we learned about months ago. Just saying "Hey guys, look at our kinda cool concept! Come back later for the price, the SKUs, the specs..." shouldn't be enough for eveyone to overhype this console. We don't have any real news, so we should still be asking the same questions: how does it work, how well does it work, which games, for how long, and for how much? None of these questions were answered today. I'm not worrying (I don't plan on buying a new console for years so none of it should impact me), I'm just curious and I like to really analyze the consoles and what can make a success or a failure. Until now, it's still unclear and everyone is overhyping and predicting the success of a box we still know almost nothing about.
