Pretty sure it's not. I think they're meant to be Optimus Prime (duh), Swoop, Starscream, Soundwave and Lockdown, in that order. I could be wrong, though. I'm sure about Optimus, Starscream and Soundwave, since I've played the game, and also, they're pretty obvious. I believe that is indeed Lockdown, and I know they have the Dinobots in the game, so I assume that's meant to be Swoop. EDIT: Oh, I think you mean in the Optimus Raceway set. Which, if that is the case, then I believe you are correct, unless it's meant to be someone like Galvatron.
It's "Ultimate Megatron Pig" (plus "Ultimate Optimus Prime Bird") according to the packaging, which we've seen previously.
They should make deluxe Angry birds transformers figures, don't you think? And those figures look nice.
