You do know win 8 on arm wont run x86 programs.
@miksu can you scroll with the mouse wheel ?
Yes but it's not a great user experience. The swiping method Miksu described definately should be implemented to mirror the touch interface that Metro was clearly designed for.
I expect it will be in the final build, it's too obvious a feature not to include. The again, looking at the games explorer in W7 I wouldn't put anything past Microsoft these days.
