The currently Windows Mobile and Android Smartphone HTC Sense is rumored to be heading forward to release a Windows Phone 7 version, too.
There will be a great improvement over at Android version since HTC Sense is preparing their Sense UI to pair up with the next gen Android 3.0 Gingerbeard. As for the Windows Phone 7, Microsoft decision about to leave lesser customization/limitation for OEMs did not discourage HTC Sense to hit the Windows 7 button. HTC Sense still intends to tweak their setting to suit Windows Phone 7 OS and stuff their Sense UI into the system.
Expect HTC Sense to release their Windows Phone 7 version in this Q4.
