looks like Sony is moving away from the XMB UI in it's newer products, noticeably missing from the PlayStation Vita & Sony's New   STR-DA5700ES and STR-DA3700ES   AV Receivers that ships in November  with the "activity based UI" that's said to be easier to use than the XMB (XrossMediaBar), could we be seeing the new activity based UI in a future FW update for the PS3?
