From an online store in Brazil (of all places), some new Transformers products have leaked, and none of it is main line stuff either.
(and the online store is now not working, so the sudden attention might have killed it )

Hero Mashers look to be a new(?*) toyline concept by Hasbro, that feeds off their Construct-Bots concept - interchangeable parts to mix-n-match.
So far there are Marvel Superheroes released in the Mashers toyline, but now it looks like Transformers will be next... so now you can make your own "Autobot X" toys.

The first six shown are (movie spoiler) Grimlock, Optimus, Starscream, Bulkhead, Bumblebee, Bludgeon.

Since the source site is currently down, I can't see if there were any dates or prices listed with these... as the fans on the two global fansites didn't mention any specific details or if there was a lack of details.

The one detail that was fortunately copied at the Seibertron site, was that the movie character figure mentioned above, has electronics but is still interchangeable with any other Masher.

(* I had a look online for info on existing Mashers, and as far as I can tell, they are out... as the Hasbro site has them listed as released... but I couldn't find anything older than a couple months, so might be really new)
