This was on WrestleZone:
Petey Williams said during TNA's UK tour that the TNA iMPACT! video game will feature downloadable wrestlers (depending on the system) which will allow users to add characters to the game. The game is due out on 9/8.
That'll make up for the poor roster size, but I've got a PS2, so I'm screwed...
