That is absolutely brilliant.
Anyways, it could be a new... wait for it... GAMEBOY?? The Third pillar resurrected.
I can't see Nintendo announcing a successor to the Wii or the DS at all this year.
The Wii has 4 huge AAA games on the way this year (Mario, Zelda, Metroid, DQ10) plus whatever Nintendo is holding back from announcing (Pikmin 3, Starfox, F-Zero)
I honestly think they will do a double reveal at E3 2011, Wii's Successor and the DS2. We'll get an early 2011 announcment for the DS2 but E3 will be where all is revealed (specs, games etc)
