Unfortunately, all, as the official site policy notes:
"Administrators,
moderators, and other Connection staff members, as well as Microsoft
contributors and MVPs, cannot confirm or deny the accuracy of any
information found in discussions of rumors or speculation in this site."
However, what I will say is that I'm treating everything I hear about future developments with Windows Mobile - including 6.5 - with a huge grain of salt. Honestly, I know almost nothing about 6.5, let alone about the future beyond that. Sorry!
