I still don't get this whole notion of VR being a big thing.
VR is the nichest of niche technologies, affordable to a miniscule portion of gamers, releasing (maybe in the next few years) on hardware that totally isn't ready to support it (from a business viability POV).
There may well be lots of noises made about VR at E3, but actual tangible content is likely to be between zero and sod all, with a further thimble full of content coming over the next couple of years until the whole concept is shelved and forgotten about. Just like VR was before. Then VR tried again. Then 3D tried. Then Motion control. Now VR is having another shot.
These 'imminent inevitable futures of gaming' keep taking potshots at the
Person->Controller->TV paradigm and fail every single time.
I really wish that instead of chasing these dead end technologies, the energy used was put into revolutions that would actually affect gamers. ALL gamers, not the 1% who can afford/care about/physically endure these N-dimensional McGuffins, but everyone who games.
An AI revolution would benefit everyone. Pour millions into new game AI research instead of niche plastic. Produce complex AI middleware. That would elevate gaming as a whole.
Anyway, to bring it back on topic: My E3 prediction for this year is lots of VR promises which will end up being broken, along with backers' hopes, dreams and finances.
