Has anyone else noticed that some games have had screenshots changed in the game's page? Like for instance, Witcher 2's image of the lady running away suddenly has Santa popping out of the side waving at you. Anyone notice any other games that had this sort of change/edit?

This happened last year. It was a scavenger hunt for a contest to win every game in the catalog, if I recall correctly.

Perhaps it is happening again this year? Maybe we will get some news soon?

This is nice
