I don't know if I'm looking forward to season 3 as much now. Not that this wasn't a good finale, but now the first 1/3 to 1/2 of season 3 is probably going to be spent on [spoilers]everyone searching for each other to meet up again, with them slowly regrouping. Once all but Prime and possibly Wheeljack are together they will go back to the base where they'll probably find Optimus gone. At that point the rest of the season will probably be spent searching to find Prime while avoiding Shockwave's beast minions[/spoilers].
