Nice setup, but I think you should remove all the GC compatibility. Nintendo only goes one gen back. GC would then be added to VC.
So for me I'd see:
a quad to six core CPU
high end... dual core GPU.. stick with similar base as Wii's to allow backwards compatibility.
1G to 2G RAM
16 to 32GB flash storage. (expandable SD card again)
2 to 4 USB ports
Wireless N
Proprietary HD media.. similar in capacity as Bluray, but no video playback... like Wii is currently to DVD.
Fully backwards compatible with Wii.
Can copy over all channels/VC content, once and renders it removed from original Wii.
More enahanced Wiimote/nunchuk with something of a cross breed to Kinect and Move/Wiimote and vitality sensor built into remote.
online continued off of Wii/3DS. More push for media playback and probably unified ID number so no more friend codes... but not as nice as an actual username. Will allow some sort of naming and will have leaderboards and other similar content as Live or PSN.
In the end it'll be more powerful than PS360 at a starting cost of $300.
