Play as Grimlock voiced by Gregg Berger?
shut up and take my money.
Nice to know they got some of the old gang back. Cullen (Prime), Welker (Megatron, Soundwave), Berger (Grimlock, Longhaul), Michael Bell (Sideswipe, Scrapper), and Dan Gilvazen (Bumblebee). The only guy who's not voicing a character that I would otherwise expect is Corey Burton (Shockwave, who is voiced by a guy I've never heard of).
Based on the TF wiki page, there are some interesting omissions. Most notably Jazz. Ironhide too, though I suppose it's possible Cullen doesn't want to pull double-duty (or wasn't paid to do that).
EDIT: Seems like the initial reviews aren't bad either. It's apparently what you'd expect out of one of these kinds of dynasty warriors knockoff type beat-em-ups, but it's a fine example of the genre and the shiny, well-produced transformers coat of paint it's slathered in makes up for however stale the genre might be.
EDIT 2: Just found what seems like an audio flub in the trailer. There's a part where Bumblebee shrugs and says "sounds like fun!" at about 40 seconds. But that is not Dan Gilvazen's voice. Sounds more like Michael Bell. That would actually be a great G1 homage if it's not just an editing screwup by the trailer guy, because the G1 cartoon was full of moments where the wrong character was animated delivering a line. I remember in the Dinobot origin episode there's a bit where Bluestreak is animated giving the lines of 3 different characters in succession, none of which were him IIRC.
