SE did drop the ball with X10 for not upgrading it to 2.2 (and took a hell of a lot of time to get 2.1) but as long as their new handset ships with the latest build of Android (2.3) I will see no probs with getting a SE handset.
All Android handset manufacturers so far have only updated to one build higher than stock.
