NetherRealm recently announced that there will be a special live stream at PAX West next weekend. Details are said to be coming soon.
While I was looking at the PAX West schedule, it appears Mortal Kombat X is slotted for a "Console Tourney" on Friday at 12 NOON PST. Injustice 2 is also slotted for a time on Saturday at 7PM PST under "Console Tourney".
This could very well be something as simple as a tournament with both games, but who couldn't help but wonder if we'll see something else.
