One thing I like about VR is that, from the demos i've seen, it looks like we're finally getting more variety back in environment design. Not to say we haven't left the Distressed Modern Industrial era behind, but there's a lot of much more colorful design from what I've seen.
That's not because it's VR. We've been having professional "indie" games and publishers pushing that aesthetic for quite a while. It's just that these indie groups are the ones willing to go into VR since it's compatible with a strategy of attracting a small dedicated market, rather than an extensive one, whereas the AAA devs can't afford to take risks.
I dunno. Omnitreads are just so expensive, and it's hard to picture a way to make them cheaper. Pure motion tracking with some clever illusions would be free, but it demands space that many people just don't have available.
I suspect that full-mobility VR won't see consumer success in this round. But headsets and hand controls don't really require that kind of thing anyway; walking with a joystick or using one of several other mobility solutions that creative people come up with should end up being adequate; people learned to deal with motion sickness for the sake of cars, after all. However, I do suspect we're going to continue seeing games made where you're in a space ship or other vehicle, and can only walk in an area the size of what your peripherals allow and otherwise move the vehicle (see for example Hover Junkers).
All I can say is that room-scale VR is a perfect fit for strategy games. Just have the map scaled to the available walking space, and the player walks through it like a god, directing his minions.
While I agree, no dev seems to be following this train of thought. Perhaps because graphical gimmicks don't tend to track particularly well in the strategy market, and strategy gamers are quite discerning in game mechanics, making the barrier to entry higher than a lot of the simple games and glorified demos we're seeing so far. It would be awesome to play, for example, Stellaris, as a giant galaxy-striding space god, but I don't think we're going to see strategy game engines supporting that for around half a decade.
