Two things:
- Win8 is unlikely to be adopted to by businesses. It's quite different, and they are only just starting to think about Win7.
- Version 1 of any product is going to need to be bedded in / ironed out before it gets real traction.

So, no, there is no point in waiting. It would be worth supporting the initiative by MS, and promoting their use for personal activities, but not for business. Yet.
