That may be the case but VR manufacturers needs to think hard whether they will stand a chance to go mainstream if they require a full room with no furniture.
You don't necessarily need a full room with no furniture, just a big enough space in a room, which can be temporary - for example, I use half my kitchen with the table moved back. You only need 1.5 x 2 m minimum (though that is a little restrictive).
I think 100,000 early adopters given the current very high price suggests going mainstream isn't much of a problem.
