I've been interested in the Thirteen since I had heard about them (pretty much started with the Fallen), I was at BotCon when they revealed Solus Prime's existence and feminine body-type, as well as revealing Nexus Prime's concept drawing (knew he was one, but didn't have a picture last year, now they're confirming he's the "first combiner"). They also revealed there's going to be an "original beast" amongst the thirteen as well as a "Minicon". For the hell of it, I was on TFWiki's Thirteen Original Transformers page, and I noticed something on the picture they have up. This one: Look at the head at the fourth from the left position, third from Megatronus'. They just revealed to the public that there'd be a Minicon in the 13 not even 48 hours ago (from this post). I knew they'd been working on them, but damn, it's still kinda a mind-fuck to me.
