Sly Cooper: Thieves In Time - Estimated Sales.

[pokoko]

.7 million, I think. This type of game on the PS3 is all about legs, except that those legs are going to be cut off by the PS4.

Still, I wouldn't compare it to Ratchet & Clank straight-up, as I imagine some of the later R&C games have a higher rate of sale on PSN than most other games.
