I think they must have had another preview event, or they weren't allowed to release these images until now. This set of images features the four Gen1 Autobot Headmasters, as Titans Return Deluxes, with comparisons to the original 1987 toys.

And it looks like another Hasbro Asia exclusive sticker sheet was given out as well, for the first wave of Deluxe, Voyager and Leader Titans Return toys.
