im thinking that this game will have different story line patterns for the five teams like with gaoranger and hurricanger shows, accept it's all in one game, it will probably have at least 5 levels guessing from every team, it was that many in gaoranger and hurricanger, but who knows? probably the solders in scan are probably just random used in a special mode, so it's going to be a fun game.
on the gokai changes, they will probably change into the current teams in the game dont know yet, maybe some addon teams just for gokai changes probably deka, magi, gao, two more depending on their mecha releases.
