It seems to be rather unlikely, but Pocketnow has been tipped to an e-mail between Sprint customer services and a Touch Pro customer where he was reassured that this was in fact in the works.
Thank you for contacting Sprint. I understand your frustration and appreciate the opportunity to resolve your issue.
Currently, we are working to launch the Windows Mobile 6.5 upgrade for HTC Touch Pro.
Although, no official release date has been declared for the upgrade.
However, as soon as the upgrade is launched, we will inform our customers with high profile promotions.
I understand that there are lot of customers waiting for the release and I can assure you that our technical department is working hard to make it available soon. I appreciate your patience and understanding in this regard.

We value your business and appreciate the opportunity to address your
concerns. Visit Sprint.com/mysprint if we can be of further assistance.
Of course in all likelihood the support person is either mixing up the WM 6.5 update for the Touch Pro 2 or does not know what they are talking about.
But then, who are we to squash faint hope?
