You could stand up on any version of the Oculus Rift, but you won't be able to move.
That's what those "Touch" controllers will be made for, room-scale VR.
But for sure, you wont be able to move more than the Vive, probably because of accuracy of cameras.
Moving around is still possible with the Rift, and will be fully functional with those
future controllers.
Then for the price, I'm pretty sure the actual price of those controllers + Rift will meet the final price of Vive.
To be honest right now, the best VR experience is the Vive, mostly because of number of games available on Steam VR, but especially since it was
made for room-scale VR.
I ordered the Rift mostly because I couldn't afford the Vive (high bull stuff europe prices), and I don't have much room for room-scale VR. Currently waiting for June delivery.
