This has nothing to do with anything: the average size of the MK9 DLC packs (1 character and 2 skins) is 84 MB, but the leaked Lobo file is 162.82 MB -- it's about twice the size. What would account for all of that extra data? I'm hoping we'll get more than two free skins this time around.
Probably a boat load of costumes, if they really want to get to 100 then they'd need to do about 12 per DLC character (if there's only 4).
