All the hype I've heard is that they've rewritten it for 64bit while still being able to read and use 32bit and even 16bit (like word processing programs, apparently it's one of the reasons you can't have your ystem completely optimized for 64bit computing because supposedly it won't even recognize the 16bit apps) apps.

If you are wondering if you can buy the 64bit version of Vue6 right now (well, when it's released...), while wondering if you have to wait for Vista, you can get the XP 64bit version of Windows. You don't have to wait.
