Back during TGS last year where Sony showed the video that the screencaps in question is from, they announced a handful of Move games.
Ape Escape
Champions of Time aka Sports Champions
Eccentric Slider aka Slider
Echochrome 2
Motion Fighter aka The Fight: Lights Out
Motion Party aka Move Party
The Shoot
Sing and Draw
Tower
Based on this list, I'd guess that the unknown game in question is the "Tower" game.
