I am not tired with TF by any means but the original '86 explored the concept of races beyond Cybertronians such as Junkions and Quintessons. Whilst I don't expect the core of TF to be diluted isn't it time to freshen things up with new conflicts beyond Autobot vs Decepticon and add some new motivations to the mix. For example rather than a war for energon, the Quintessons clone Prime to create a Nemesis to lead a new army whose purpose is [insert despicable motive here]. Similarly breakaway factions could be interesting. They've been explored in the past but as short lived distractions e.g. Starscreams & Combaticons. Whilst TF Prime has certainly thrown some welcome curve-balls and is a solid show new threats and new allies wouldn't go amiss, would they?
