Yeah, there was a thread before and I think our thoughts were something along these lines... We totally plan on updating to Drupal 6, but the task is going to be monumental and very time consuming. The reason is that three key APIs (menus, forms, and install) have been changed from Drupal 5 to 6. Anyone who's used Ubercart at all knows that most of what we're doing is creating menu items, working with forms, and using install files for all the configuration.

This doesn't mean it will be impossible, but we do want to get version 1 out the door before we start the upgrade. Moving to Drupal 6 will probably have to wait until then and we should get version 2 out the door not too long after.

As for Drupal release cycles, beta and release candidate stages usually last a couple months, so we shouldn't be too far behind. Hopefully I'll pick up some more developers at Drupalcon to pitch in the effort!

Thanks for posting the link zmove, I hadn't seen that yet. It really is great news for Drupal.
