things aren't ready for this unless they wanted all the gamers to fuck off. Gaming on linux is a huge part of the already small percentage increase in linux use and a lot of people are just starting. Suddenly not having a bunch of games work or some not without advanced hurdles and probably being told it would be easier to pick another distro is too much for newbies who may just give up and go back to windows.

hopefully hopefully valve will move along with 64 bit steam and wine's wow64 functionality improves before the supposedly inevitable no choice but to drop 32 bit release.
