Not likely. They are not going to update the XV6700, either, which is a
newer phone. They will have (maybe) a new Palm unit that might support WM6.
Sadly, the Treo along with Palm seem to be withering away. I used to have a
650, but got tired of the 6 year old OS that could no longer do much. Having
used WM5 and WM6, there is very little difference except for HTML mail,
which you can get with Flexmail or other add-ons in WM5 if you really want
it. Both are based on WinCE 5, by the way. The differnces are mostly
cosmetic.
