According to the German boys at AreaMobile, HTC has confirmed that the Diamond 2, Touch Pro2 & Snap will get a free upgrade to WM 6.5 and new  TouchFLO UI (probably the same as the one seen in the leaked roms here). What I wonder now is, if does devices (TP2 & Diamond2) get the new TouchFLO UI what are the Leo & Firestone going to bring to the table besides improved hardware ?
