Could this possibly be Tankor / Octane - as speculated by some fans on TFW, and if so, could this be the first triple-changer to appear in the movies (not counting Soundwave because lets face it, his three modes aren't enough to call him a true triple-changer despite the sticker on his packaging claiming otherwise).

Personally, I'd like to think that this is Onslaught confirming that maybe we'll see the Combaticons
