This could easily be a mixture of "CONFIRMED" vs "HINTED" given the translation + author's desire to hype the game. Here are my guesses:
-24 fighters in roster: Rough estimate. Maybe 24 + DLC? Could easily reach 28-30.
- Looks like Johnny and Sonya are major players in the story. Sure. Major part of the story but Cassie is the only one playable. Makes sense.
-Sub Zero is not Bi Han: Noob is stressed to still be a separate character. However, its noted KL went Cyber. Seems likely to be a new Sub Zero. Will be answered in story mode. Nothing really new or confirmed here. New SubZero. Not Bi Han.
-Kotal Kahn is described as a mystical Mayan warrior. Sure.
-Kotal Kahn IS SHAO KAHN's SON. The exact translation, as far as I can make it, is 'Kotal Kahn...will prove to be Shao Kahn's son in the story mode': Ok. So NRS said there's no relation, however he shares the same name with their mainstay villain. Like someone else noted, he could be a spiritual heir or disciple. Despite what NRS has hinted at, I find it much more likely that NRS would mislead us than they would make 2 characters share a surname and not be related. Huang Lao? No relation to Kung Lao, right? lol.
-Stage fatalities confirmed, natural to MK: Sure, why not?
-Ed Boon says: there will be different variations of Johnny Cage, Sonya Blade and Liu Kang. "Is Liu Kang in?" "But of course". So looks like those three are confirmed. "Liu Kang, while not confirmed, is certainly in". Possibility of a mistranslation: Johnny and Sonya could be in the story mode in different incarnations. I seriously doubt they'd consolidate to Cassie Cage then have both Sonya & Johnny, too. Liu Kang will mos def be in the game, probably playable or a major story element. Could be a zombie and die in the story.
-DLC further confirmed, guest character further confirmed: Of course. This could bring the roster above 24 to 28-30.
