I get the impression that the "Generations" branding is going to be used for the main line of converting/non-gimmick Movie toys this time... as maybe Hasbro thought a separate "movie" packaging/series would not be supported by retailers enough.
On the flip side, retailers here have ignored Generations for the line with the media tie-in (TF Prime/Beast Hunters). Toys for a big budget movie are more likely to be bought by the retailers I think, and if the stores are buying Generations it might mean future "classics" waves/series may have more of a chance of turning up here.
