The Kinect answer to Wii Sports has a new title coming out. Kinect Sports: Season Two will be hitting shelves in October and the team behind the new game is demoing part of it at PAX this weekend (no awkward football bros this time, sorry). The baseball section of the game is open to play right now, so if you're at PAX, into baseball and like flailing around, go try it out.
Kinect Sports: Season Two will feature six new game types, including football, baseball, skiing and darts (is darts a sport?). I never played Kinect Sports and can't say I'm sorry about that. It will probably be a hit with families though, so if you've got kids this may be something to consider. It might also make a fun game to play while drunk, so there is that.
