There is no denying VR sounds cool. In some cases it might actually be cool - I'm thinking particularly of racing / flight / space sims where you sit in a cockpit and the range of movements in game roughly correspond to real life - you sit in the game, you sit in real life, you have buttons and controls in the game, you have buttons and controls in real life.
But for other kinds of game I really don't see the benefit. Yeah it could be used for first person shooters (for example) but then the game has to somehow reconcile a person running, spinning, jumping, aiming, shooting, standing, crouching and throwing stuff to someone in real life sat on a couch. It's likely that it will be extremely disorientating and puke inducing.
And aside from FPSs what can we expect? Probably some lame jump scare horror games. Probably some table top style games. But nothing that particularly justifies the experience. I bet most games will work as well if not better in 2D.
I expect you're right about cockpit games, and I'd add giant robot cockpits to your list. They will work and work very well, and that might be enough to drive a major market.
I also agree that FPSs that are anything like modern FPSs just aren't going to work. There may be FPSs, but it will be like Rainbow Six with the realism turned up to 11, otherwise they will make you sick.
You left out a couple of major categories though.
God games? AWESOME in VR. You control the view, and you don't have to pan very fast across the map if you don't want to. You're looking down at the little buildings and little people doing your bidding. It should work quite well.
RTSs, same thing, though possibly with faster map motion that might not work for some people.
Many styles of MMOs should also work great in VR, especially first person MMOs. Third person should be fine too, and much like the god game/RTSs as far as experience is concerned.
There's a pretty large market, even of established categories. Undoubtedly there are significant adjustments required in terms of rendering and user interface, but all of that should be possible.
What's most interesting is what will be invented because it's possible in VR and just can't be done on a flat screen that doesn't convey a stereoscopic image. Nobody knows what that might be. It will take a lot more units in a lot more hands to find out. Oculus Rift may make that possible, and considering this price, it will probably happen. People easily spend that much on a new monitor or new TV, so why wouldn't they spend it on a Rift? It's another display device, like the others.
