The two video shirts are very cool (I will want a Men's L and wife will want a Women's M in the Pac-Man design) I also like the red 'Stern' pinball shirt (would be awesome in a hoodie.) The blue pinball ones...hm.
We're a little torn on one of the pinball designs

Retro Pinball 3

To me, the '8' in the middle of this design looks upside-down. Also the script on the flippers is sort of meh...

Again, the script writing underneath the flippers looks out of place. Also, the condensed kerning on the type at the bottom is virtually impossible to read with the black outline.
All that said, i'm always excited about the next shirt designs each year, so you guys are doing it right.
