not aware of any core applications that are moving to 64 bit, or need to be. I have no idea when/if any of the existing software will move to 64bit, and hardware/software just isn't the hold up in our business practices - if there is a charge for the upgrade, there is no chance we'd do so.
Well, at least by the end of 2006, not before :) Gamers - that is where you will see it first.
