I don't think we'll see Elfman all too soon.

All the characters that were revealed or shown in shadowy silhouettes are either from the battle team (for the last GMG event) or the rescue team. If they show anyone who's not yet "in the shadows" it's most likely going to be Mirajane, Pantherlily and Yukino, rather than Elfman.
