iD/Zenimax, Epic and Valve would all see the hoped for $250 000 as chump change for a dev kit. Split between the three and it's essentially nothing. My guess is Microsoft or Sony would love nothing more than to tie up an exclusive peripheral for their next-gen consoles, and buy the company outright (as MS did with Kinect). This would be a true differentiator.
That they're looking to Kickstarter to sell $300 dev kits makes me think something very bad is going unsaid. My wild guess is that they still give people headaches as with previous VR attempts, and no-one is willing to put money in the pot with the expectation that it is unsolvable.
People putting money into this are as crazy as those who put money into the OUYA.
