This biggest problem is not the distrobutions, Linux64 have been avaialble for more than a year. The problem is with the hardware manufacturers. Except for server class hardware, most commodity hardware will not have 64bit drivers untill windows reaches Gold stage. This means that there is limited driver support for linux on the 64bit platform as well, since many drivers have to be reverse engineered.
