Just read this on an MK site from an interview a few weeks ago with Ed Boon:
"Boon also mentioned that they plan on releasing a patch (note updates on themortalkombat.com) so that competitive players can keep up to date on all of the changes that are going in to the game, as there are tons of tweaks to be made here and there."
Yeah like probably requireing you to have 3.61 FW to use the DLC...which I'm sure the patch will be coded that way to begin with. Killzone 3's newest update patch was coded with 3.60 keys. But I guess we'll just have to sit back and see!
