The trophy/achievements listing has been released, but be aware of SPOILERS if you go for that sort of thing on computer games... and don't go further into this topic if you don't want to see details from that site.

Only 19 achievements with this game, plus 11 "secret" achievements.
With only 7 chapters, this is looking like it will be a quick game, but with all these Gen1 Voice Actors, it might be enough fun to play a number of times before getting sick of it.

Some nice art is included for those not caring about spoiling who the level bosses are. Click on each achievement to see full-size artwork.

There looks to be seven chapters to the game, with Devastator being the boss of the first chapter... just as it was noted at SDCC, that he wasn't the final boss. (I didn't think that he'd be the first boss though, as it suggests he's the easiest, despite being the main focal point of the game's marketing.)

Chapter 1 - Devastator
Chapter 2 - (unknown) it notes Insecticons though.
Chapter 3 - Blitzwing
Chapter 4 - Menasor
Chapter 5 - Soundwave & Cassettes
Chapter 6 - Shockwave
Chapter 7 - Megatron

And the Autobots you can play as - Optimus, Bumblebee, Sideswipe, Wheeljack, Grimlock.

It is interesting to see that there is character art for Nova Prime, using the Voyager Generations Optimus toy as its base. Even if it is not likely to be a toy, it's going to happen now as customs and alternative sources.
Speaking of artwork, the ones that have toys so far are drawn that way, while characters like Blitzwing and Shockwave looks very much like the Gen1 toys, so I doubt that that means toys are coming. (there is a Legends Shockwave toy next year, but this one doesn't resemble it like the other toy characters on the game)
