128-bit?
As far as my knowledge goes, Vista (the good versions) are both 32-bit and 64-bit friendly. This is the main reason why I'll be picking myself up a copy of an upgrade to Vista Home Premium. Perhaps you're thinking of codename: Vienna which is the next windows to come out after Vista. Though the technical details of this OS is very, VERY minimal...
But yeah, I think you should get your computer now and put on maybe windows 2000 or something cheap, then get a Vista upgrade when it's released towards the end of this year. I wouldn't worry about all the bugs and tweaks as they'll eventually be fixed up via Windows Update and Service Packs.
