I was talking to my son this morning and we were thinking how cool it would have been if the Predacons eventually combine to form Predaking and then The Dinobots come in and help the Autobots and eventually combine themselves.
Haha that would work But yeah pretty unlikely... I'd be happy with just the Dinobots, even if they couldn't combine.
Spoiler According to the toys and the small preview we've gotten, Predaking is a singular entity, not a combiner.
Dinobots might show up, the comic they're in is supposed to lead into season 3 Transformers Prime: Rage of the Dinobots - Transformers Wiki
