The code from which TouchFlo3D/HTC Sense in constructed will apparently still overlay Windows Mobile 7, with the software apparently already checking for the presence of the OS, even in current builds.
XDA-Developers member CookieMonster found this code in Manila 2.5.1922 lua scripts (from 6c219600_manila on this occasion):
if HomeMachineStatus.WM7Device.Value then
IsWindowsMobile7Device = true
PredefineItem = 1
HomeItemCollection = HomeManager:GetHomeCollection(1)
IsWindowsMobile7Device = false
PredefineItem = 0
HomeItemCollection = HomeManager:GetHomeCollection()
This development is somewhat interesting, and raises interesting questions regarding user interface innovation in Windows Mobile 7. Given that the Windows Mobile 7 UI will still be hidden below what every other OEM is using, will we see as flashy an interface as on the ZuneHD, or will things remain relatively pedestrian, as in Windows Mobile 6.5 now?
