Actually, you're right, I was thinking about the multiverse of MK and there's still the movie universe which includes the first film, Annihilation, Conquest, Defenders of the Realm, and the proposed Devistation. Then there's Rebirth as well as Legacy. I think those are the only (other) official universes in the multiverse.

And you're right about the comparison between the New/Prime Earths and the Original/Alternate timelines. But take in mind that MKvsDCU, assuming that it is canon-ish, would be a part of the original timeline. At the end of MK3/Ultimate 3/Trilogy, Shao Kahn was still alive but defeated. This would say that the beginning of MKvsDCU would be right in having Shao Kahn trying to rule the MK and DC universes as a merged universe so it would be canon to the original timeline. Whereas, at the end of MK9, Shao Kahn dies and, therefore, MKvsDCU wouldn't be canon to the alternate timeline. Moreover, not even MK1-MK: Armageddon wouldn't even be canon to the MK series because we now have an alternate timeline due to MK9, with history being rewritten and all.
