Yea, I feel like room scale is huge for marketing purposes and I'm sure it's amazing when you try it at demos, but it does have the vibe of being rather gimmicky long term - at least for this generation of VR.
The combination of space needed, keeping track of wires so you don't trip and the further immersion-breaking of being told there's a rl-life wall or obstacle when there isn't one in the game makes it feel a bit wiimotey.
I'm sure there'll be fun stuff to do with it - but I think it'll be a lot more limited than many think.
I think it really doesn't matter much which one you go for - they're both going to offer amazing and very similar VR-experiences and possibilities (once the rift controllers come at least) and hopefully we have no, or very little, of the exclusive nonsense happen for PC-based VR.
Fun times ahead no matter what
