As much as the touch controllers are a sweet dive into the actual world of the game, I really do see the future of VR being augmented with controllers or at the very least a touch controller with a control stick of some kind. As I said in a previous thread, I would hate for all future built-for-VR titles to sport the teleportation movement that seems quite popular on the Vive.
There are limitations to both solutions, room scale and seated, but I think I'm coming around to Oculus' view in that VR is better suited to a sitting/static position rather than walking around when it comes to games. I simply cannot see full fledged titles like Minecraft, Doom, Assassin's Creed, or any other AAA game sporting the teleport mechanic. So far, the Vive has a leg up on the touch controllers but most games I've seen are on rails, in one static room, or use the teleportation mechanic. In all three instances you're still only essentially in the same spot, physically, so I'm beginning to lean more towards the Rift than the Vive for longevity.
I think once developers see the limitations of room scale for actual games, not tech demonstrations, then we will start seeing a hybrid of touch and control based movement. I guess I'll wait until more VR titles pop up before I make a decision. Sure is nice to see this new tech unfold as each developer does something different with it.
Always a problem.
