Sony's been spotted patenting a "User-Driven Three-Dimensional Interactive Gaming Environment" - technology that works like Kinect.
Move Fitness is Sony's first foray into the increasingly crowded digital gymnasium Nintendo opened four years ago, when Wii Fit first started upsetting fat people by pointing out they were fat.
The best fitness games aspire to be four things at once: a stepping-stone, a supplement, a motivator and a distraction. They're not meant to be a replacement to 'normal' exercise, which is the usual assumption of habitual point-missers.
You may want to do something about the terrible state of your personal fitness - or, indeed, fatness - but the step from slobbing on the sofa to sweating in an all-too-public gym is considerably bigger and more daunting than the one to the fridge for another sausage roll.
Thank goodness the year-late Call of Duty: Black Ops only costs £47.99 or €59.99 on PlayStation Store - for a moment there I thought it would be more expensive than Modern Warfare 3!
As balance, the "ridiculously absorbing" Might & Magic: Clash of Heroes HD has halved in price to £6.29. Definitely buy it.
Also worth serious consideration: excellent games Beyond Good & Evil HD at a new price of £4, and Lara Croft and the Guardian of Light at a new price of £5.
Sony has unveiled a Move exclusive fitness game called, sensibly, Move Fitness.
It's due out this year.
Move Fitness does what it says on the tin - offers exercise games based around the strengths of the Move controller.
