In the same situation, and I'm actually far more hyped for room-scale tracking at this point to tell the truth. (But now with the free Rift I guess I'm somehow more hyped again
)
Room scale still has a lot of question marks for me... least of all that I don't really have an appropriate space at home... but that said, I figure getting the touch controllers and a second camera and trying out some of those games will let me know if I want to spend whatever HTC and Valve are asking for a Vive, and if it can work inside my house.
Plus, it's always sounded more likely that Vive stuff would also work on the Rift (so long as you have touch) than it does that Oculus exclusive stuff will work on the Vive (though I know there is absolutely a chance there).
I was going to go that route anyways... but I'm sure this sways a lot of people to wait until they can try those things out with their free rift to at least get more a sense of what the Vive *might* be like in their living situation.
On the contrary what harm is there in letting people make informed decisions. They clearly want to control messaging and exploit people who are impulsive.
You can't buy it yet. By the time you can you will have all the information you need, and you will have time to figure out if you want to buy it or not before launch. Presuming they don't sell out day one (and it sounds reasonable to expect they have plenty ready for launch given what they've been saying) I don't see why you need to figure out whether or not you want to buy one before you can...
