It is the Buster mold, but it looks like the standard paint apps, rather than the nice chromed stuff they got on the original release. No swords, either. Still, it's got the remolded chest and abdominals to reflect the movie's redesign, and BFGs that would make Ironhide turn green with envy.
Apparently, the jetpack is compatible with all versions of the mold, however. It does make me wonder whether the retooled abs make him incompatible with Jetfire.
