Five most unlikely E3 2012 announcements

These new gaming inventions won't happen. But if they do, you saw them here first.

The days before E3 are always filled with endless pontificating and predictions. The lesson? Throw enough predictions up against the wall and something is bound to stick. Of all the ideas we've heard, you'll probably agree that these are the least likely to happen, although each one still seems like a potential blockbuster to us.

Nintendo SmellDS
Nintendo finally explores the next dimension in handheld gaming: olfactory. (Nintendo promises: sense of smell not necessary to enjoy SmellDS; scent slider included.) Reggie Fils-Aime promises, "You've never smelled Super this."

Double-glasses 3D
We tried regular stereoscopic 3D, didn't catch on. We tried no-glasses 3D, not much better. The answer is finally here: combining two sets of active-shutter lenses for extreme depth, with only a slightly increased chance of migraines.

PlayStation Vita 4K
Now with a DoubleRetina(TM) display for graphics, for details the human eye can't see! With 4,000 lines of resolution, this upgraded handheld console needs to store some of its pixels in another dimension.

The ultimate social media game. Free to play, except for the parts where you pay to play more for free.

No-motion gaming
First there was motion gaming, and now, the newest post-Kinect, post-Move, post-Wii invention: a tiny controller that fits in your hand, complete with its own physical buttons. All the convenience of motion gaming, without having to actually move around.
