ESM: clem has said somewhere that he is now (as a trial period) working on mint full time, and that x64 is his current priority (now the upgrader has been released). As always, mint only releases when it's ready, so if you prefer a fixed release date you should stick with ubuntu, but I shouldn't think gloria x64 is too far off. It's also only been about a week since Gloria was officially released, about a month after ubuntu, so 9.10 is still 5 months off. By all means, if you prefer ubuntu, stick with ubuntu, distros are all about choice: if there's something you don't like about how the distro is run, it's easy enough to jump ship.
