As far as stock, I was really only paying attention to Wii games, since that's the system I have. I was particularly interested in Super Monkey Ball Banana Blitz (how's that for a name?) but noticed a Barbie game (not sure which one) and several "boy" oriented ones. Sorry I didn't pay closer attention to the names.
It's true that the display holds empty boxes. The store clerk I spoke to assured me the games were new (not re-conditioned or anything like that) and when I was ready to purchase I needed to go to the customer service and request the game I wanted. I'm just assuming they were shrinkwrapped but can't confirm, if that helps any.
And yes, there were also DS games but again, don't have that system so really wasn't paying attention to the selection.
