Nowhere does it say that it 'should be based on the Tegra X2'. Dev kits are using X1 and any X2 talk is completely speculative. And we really know NOTHING about the performance of the X2. I highly doubt it will be anywhere near as powerful as current gen consoles. These claims of 'as powerful as console' when it comes to mobile power are usually always highly exaggerated when you look at what they can really do, and not just on-paper, cherry-picked specs.
Anyways, I dont know what to think. I really just want a solid, reasonably powerful Nintendo console. Something that would give multiplatform developers good reason to want to develop for it alongside XB1/PS4/PC development. That's clearly never going to happen. Nintendo wants to live in its own little bubble. Which means it will forever be considered as a secondary system for most 'core' gamers.
The idea of it being a hybrid handheld/console does mean it has the potential for more games than you'd usually get if you only got a Wii U or only a 3DS or whatever, but the console experience is going to be compromised. I also dont like the idea of having to constantly plug in and unplug the system if I want to change how I'm using it. Plus having to charge the thing all the time, of course.
I surely hope this comes in at $250 or under. If it's X2, it almost certainly wont, though. But I'm just not going to spend $300+ for something that only plays Nintendo games, sorry. Especially when Nintendo games rarely drop in price, meaning you are often forced to pay near enough full price even for years old games.
