On Nov. 16, 2011 the co-creator of Mortal Kombat, Ed Boon,
announced that a patch for Mortal Kombat Arcade Kollection (MKAK) will be available by Thanksgiving.
A day later ... a patch short.
Boon via
twitter says NetherRealm has delayed the patch. The target date for the patch's release is Dec. 6. He also mentions that the testing and approval process takes time.
