Both were good ideas but
Kinect had a silly name and silly games, a few good ones but was too early to market. Also lack of buttons.
Move worked but was overshadowed by Wiiii and Kinect, and not helped by lack of game support, or occasional poor implementation. COD and BF would have pushed it mainstream.
I will admit to being a Move user, for First Person Shooters, but most sheep played COD and BF, not Killzone nor Resistance.
