Without question! KI has started a firestorm since living up to the hype, there will be full blown competitions, etc, for KI come summer time. It's much deeper and balanced then MK, and def holds it's own against SF. KI has and will be the next Halo for MS in the fighting game genera, it's really that special of a fighting engine.
I applaud Double Helix, they not only created one of my favorite games at the moment, but I can see this game being my ALL TIME favorite fighter EVER once they are done with it!
