May want to wait man! According to PCGamer, the Vive has a better FOV:

The real test will be how it translates to gaming, but that really makes me want to hold off. Plus if you're concerned about price, I think Asus and Gigabyte is going to be cheaper.
You are probably right. I bought an HD-DVD, Zune, Betamax.... Really though the reason I went with Rift is because I don't like HTC and I'm scared of Steam support. Also the controllers are superfluous to me, but I do like the design of the Rift controllers better. If you happen to test both of them let me know what you think. I can always cancel my order.
