Personally I think with the amount of content in Deception that there really is a chance they didn't do any SUs. I think people need to be grateful for Deception as it is, having more content than any MK game in MK's history. I also think people need to come out of denial and realize there's a very good chance that there isn't going to be anything more. If there is, that's great, but I think everyone got their hopes up way too early and too fast without any solid evidence. Everything about SU's up until tonight has been nothing but specularion and false rumors. Alot of people have gotten themselves worked up and believing in something that they really have no proof exists and no reason to believe other than that they want it to. They get mad at those of us who are being realistic and defensive, but we all know that the defensiveness comes from the fact that they know in the back of their mind there's a very good chance they're completely wasting all of their time, and ours, by searching or discussing SUs and further secrets. I won't deny that I think there are some secrets, but I think it's not going to be anything too surprising or impressive, and I think those searching for them, upon finding them, will be let down. The secrets in past Mortal Kombats have never been anything great. Cyborg Smoke has to be the best MK secret that was playable they ever made. People are expecting way too much from an already excellent and beyond exceptional game. There are alot of characters people want to see develop further stories. Rain, Sektor, Sheeva, Kintaro, Stryker, Fujin. They may not be SU's, but keep in mind, the MK team has no problem bringing back old characters. Someday you may see them again as Arcade mode characters. Until then, be patience, and be sensible.
