Does anyone know what will happen to VFP in Windows Vista?

I mean: VFP 9 will work in the same manner that in Win XP? 64Bit will affect VFP? Support for dual core will affect VFP? There will be no change if VFP runs on a machine with Windows Vista, but single core and 32bit system?

I have lots of applications working out there, and my experience tells me that my clients will try out Windows Vista. I must rewrite those applications?

TIA
