you don't know what, if shake 5 (or 4.5) will run on widows?
it won't, since OSX is still OSX, even on a intel processor.
i just hope it comes out soon after the first macintel workstations hit the shelves, i need a new computer soon and feel a bit silly to buy a G5 at this point (it also feels silly to run shake under rosetta though
