I think this is a little preemptive.
Ultimates or No Mercys have been a staple of the KI franchise and to strictly never bring them back would have been like not bringing back Ultra Combos. They might of well as not even re-made the game then at that point and should of just made a new IP fighter. It is in my utmost opinion that IG and MS are trolling us right now with saying there won’t be any more for other characters. Throwing money at them when we really don’t know anything probably isn’t the best way to handle things at the moment.
If indeed they were serious about not doing Ultimates or No Mercys in the game period or rather for S3, then that is when we need to step up but since S3 isn’t even out yet we can’t really say for sure.
It would be very disheartening to hear if the #1 requested feature to bring back for 3 years now isn’t put into the game. While stage-ultras were cool, I’m sure everyone would trade them all day long for Ultimates as a replacement feature.
