Second day entry! Also, I happen to like chocolate milk much more today than I did yesterday.
The Nintendo Thought Boy.
Nintendo has already covered the touch and motion market and the new handheld will do both plus read your mind, the next logical progression. Nintendo marketing will refer to the device as the tBoy, which fanboys will think sounds stupid. Fanboys will shorten this to just Toy, which everyone will think sounds stupid.
The first game to put this feature to use will be the third Scribblenauts game. Instead of 'write anything', the tagline will read 'imagine anything'. Unfortunately, the game will be recalled because of a bug which reverses the mind-link and plants ideas in the player's head, causing them to do all sorts of illegal things all the while making it very hard for them to actually move to the location they wish to go.
The biggest success will be in the RPG genre. The Thought Boy will have multiple cameras which together will detect the physical shapes and boundaries of everything in front of it. This in conjunction with the mind-reading feature will allow for spells to be cast by moving your arms in the correct manner for whichever spell you are casting and being able to hold your concentration. If your concentration falters, so does your spell. The mic will make sure that you are intoning the correct chant. The more hardcore RPGs will make you mentally prepare your spells before the start of each in-game day...and will know if you haven't.
Ironically, the Thought Boy will be the first 'hands-free' handheld gaming device, due to the fact that it will levitate in front of the player (since you can't cast Lightning Bolt and hold the device at the same time). Or maybe it just makes you think it's levitating in front of you. In any case, the Thought Boy will be a runaway success with the LARPing community.
Doki Doki Majo Shinpan 4 will...no, I won't even describe it. The special edition of the game will include a robe and wizard hat.
Unfortunately, the release of the Thought Boy will eventually end all most of civilization when a researcher at CERN gets a hold of the new Scribblenauts game and the device emits a Higgs boson out the backwards-compatible DS slot. The followup device, the itBoy (the iToy to fanboys), will remove this slot (the WTF to fanboys).
