So essentially, to be broken down to arbitrary console war terms we can all understand:
Rift now in MS's camp. Ocolus has more exposure, a legitimate release date, bundled with a Xbox controller and almost universally approved of by gamers.
Ocolus > Morpheus
MS > Sony in the VR space.
Edit: Though I see the other camp is allready doing a great job dismantling this news to make it null and void. Should have known lol
