I agree with BnM in that Nintendo is working on its on proprietary format; holographic or otherwise. As for onboard storage, Nintendo would be stupid to repeat the same mistake they made with the Wii, i.e. not having enough of it and later having to release a patch to allow for more. If they are going to keep the VC and WiiWare (and they are), they'd better allow for third-party storage and give it at least 32 gb of onboard from the get go.
As for the processors and gpu, I have no idea what Nintendo will do, but I know the criteria that both chips will fall in.
1. It must produce HD graphics. Yes it raises development cost, but not having an HDMI out will make it seem like extremely low tech and thus not worth the value. The only way the Wii got away without it is because the Wiimote was (and is) extremely revolutionary. I don't care what Nintendo has planned in terms of new controls, but i know no matter how revolutionary it is, the Wii 2 still needs HD support.
2. It'll be extremely energy efficient and quiet.
3. It'll be extremely cheap.
4. Finally, the graphical prowess will match current consoles and not outperform them. Iwata once said that we have just about reached the graphical ceiling. I believe him.
As for the features of the Wii 2.
1. It'll have WiFi.
2. It'll have bluetooth connections.
3. It'll have rechargeable controllers with the option to put standard batteries in. (think 360)
4. It'll be backwards compatible. I'm not sure about GC support but my intuition tells me we'll most likely see that on VC.
5. Online will be extremely simple but with plenty of features we've come to enjoy on other consoles. Headset, videochat, etc. You still won't be able to communicate with anyone other than friends (as in invite them to games or chat with them), but it'll be much easier to add them.
6. The OS will be able to multi-task. That means while playing you can pause and return the main menu or receive real time alerts.
7. It'll somehow communicate with 3DS. I don't know how or for what reason, but I know why. 3DS is going to kill, the Wii already kills. But both have major gimmicks (please pardon the negative connotation). The Wii 2 will probably have a more refined Wiimote and Nunchuck (maybe with a camera attachment (possibly 2 for 3D?), but that's about it. It's going to be a very evolutionary product. The tie-in is a simple effective ways to boost sales.
8. It'll be the same size as the Wii.
9. It'll be a little sleeker than the Wii, possibly made with some metal.
10. It'll retain the channel system, but think the iPhone in terms of how it'll look and react.
That's pretty much all I got.
