Transformers might be a moneymaker, but I don't see it being huge, considering how many G1 puris- er, sorry, FANS have already cast it off just based on a couple concept drawings. But given the urchin factor Hasbro has pandered to the last couple years, I'll be surprised if it doesn't at least break even.
I already knew G.I. Joe and Micronauts were in the works, too...I think in the right hands Micronauts could be one of the best popcorn sci-fi flicks to come down the pike in ages. They already got two different sets of lore to work from, the Marvel comic and the Devil's Due comic. And plus the property has never had the Hasbro marketing juggernaut behind it, so its connection to a toy line probably won't stand out quite as much.
