I see that MKO mentions the article, and that little new stuff was in the article. They mentioned the new stuff from the article EXCEPT....these other previously unknown things:
-Konquest mode will reveal clues to doing the various fatalities, and Hara Kiri's.
-The Krypts will have a new graveyard setting with various MK Characters running around, and hiding behind things.
Ed Boon also says that they're really proud about how much stuff they have crammed in this game. Since they didn't have to spend a ton of time on the engine this round, they were able to spend alot of time building features, and hidden content into the game.
Just thought I would share this for those who don't have the issue yet.
