John Carmack has written 3D engines widely used in commercial games for decades now (most recently Rage - whatever its demerits as a game, the technology is cutting edge and the game is definitely not antique). Whether or not you liked the content in Doom 3 has very little to do with Carmack's very technical, back-end work.
When the 3dfx boards came out, they cost something like $500. But it still opened up a big market. I don't see why you are assuming that a wireless headset is necessary and will not be included. Buy a TV if you want, all you've shown is that you are not in the targeted market at this early stage. (Probably because there is no way to provide that kind of hardware at lower cost, particularly without more traction)
Carmack is certainly wealthy enough already, I would assume that his interest in VR headsets is that he is a geek who wants to move the state of the art forward (not too different from the reasons for doing Armadillo Aerospace)

Wireless VR is very important. Getting tangled in cables while you're physically thrashing around sucks. Trust me (owner of original Virtual iGlasses).
