Hasbro's too cheap to release new molds for just the movie anniversary, especially since they gotta crank out new ones next year for the live movie. My bet is minimal repainting in new packaging, maybe a pack-in like movie trading cards but probably not.
Found this over on Dave Van Domelen's site, Maisto is apparently releasing RoboRods: http://www.maisto.com/RoboRods.html
These are quite truly pathetic! Maisto has been on a bad downward slide for years now, this may be the death knell.
BTW, the 1/18th asian alternators wannabe line with Toyota cars is getting released here in the US, that should be cool even though they're stealing Has/Tak's transformation schemes.
