I haven't heard that about the Move. Theres been a few reports that the Move will be <100. It's just a glorified Wii controller, so I can't see Sony justifying such a large price discrepancy.
Hmm, I remember reading an old report that it would be priced <100. Guess it's changed, which I guess is good news, if you're into motion control that is.
Sony's products have always been priced higher than Microsoft's when it comes to PS3 - XBOX360, so I'm just saying it wouldn't surprise me if a PS3 + Move bundle > XBOX Arcade + Natal bundle price wise (considering the PS3 already costs more than X360).
