Microsoft just made clear how compatible its recently announced and upcoming Windows Marketplace, Themes and apps will be. According to these information, Windows Marketplace will come to Windows Mobile 6.5 smartphones only but it was said that there isn't a technical reason to limit the Marketplace to 6.5 only. So while Windows Mobile 6.1 phones would be, most likely, able to run Windows Marketplace as well, it's not yet planned to release the Marketplace application as a stand-alone download. Same for the new Windows Phones which will come to Windows Mobile 6.1 only as well while the upcoming Facebook application will support Windows Mobile 6.1 (and higher) Standard and Professional smartphones.

As a matter of fact it means that Marketplace application will, most likely, not offered through the recently launched (and still available) Marketplace website. As for the Themes it makes sense that these are available for Windows Mobile 6.5 only since the menu structure for Windows Mobile 6.5 changed.
