You know, one of the good things with being an old gamer (22 years on the fray here), is that it gives you perspective.

Virtual Reality is not going to change the fact that most existing games & genres are better played on a PC, with a mouse and a keyboard.

Certain games and certain genres may benefit from VR, but they're a small part of the total, and VR haves its own issues too.

Do you think that it would be cool to play a FPS in VR? Go try to stand up for one hour, holding a weapon mockup controller in your hands for all that hour. You'll learn a few funny things on human physiology.

How about a virtual interface, hovering virtually in the air so you must just raise your hands to use it? Guess how many times you'll be able to raise your arms to reach it before your elbows and shoulders start flashing warnings?

Make this experiment, place your keyboard vertically so you must push the keys rarther than press them down. Now write me an answer as long as this one, and tell me how it would feel after, say, one hour.

Virtual Reality haves its pros and its cons. And to gamers, it will be a toy... a expensive and fascinating toy, but eventually just a toy. At the end of the day, you'll be back to resting your arms on solid surfaces, and will wonder why in your VR game it feels so weird to speed up and slow down... or why it doesn't even haves those functions. (Clue: Valkyrie doens't haves brakes because slowing down is a very tricky issue. When your eyes "see" slowing down, your brain wants to check your feet, which obviously aren't there and the controller won't follow, so your brain, your inner ear and your self-perception tell you that you're looking at your feet but the eyes say "no, you're looking straight ahead" and then everyone goes bananas and you'll get motion sickness sooner than later... and so there's no braking in Valkyrie)
