For our German brethren, you lucky ducks get to update your Touch Pro 2 to Windows Mobile 6.5 with HTCs new ROM (version:1.86.407.5) today.  HTC doesn't list too much except for some typical generics:

1.  HTC phones featuring Windows 6.5 are designed to handle your daily life, with only one consideration: You.

2.  You can customize with programs, ringtones, TouchFLO 3D options, and more.

3.  Connect with the people you care about most using Windows Live, Facebook and other chat clients available for download.

4.  Backing up with Microsoft My Phone is as easy as typing in a username and password and selecting what you want to back up.  Everything else is automatic.  You can even let it run in the background while you surf the net, chat with friends, or have it just resting in your pocket while you relax on the couch.

5.   All this and increased convenience with a one stop shop for applications available for free and for download in the brand new Marketplace.

Still, if you're not using a custom ROM already and want the official version, well here ya go.  Get it here.
