Personally, I rather SNK take more time to make a better game than buy a crap game for an early release.
I truly hope KOF XIII can make a better number on sales. SNK put this much effort on it, they deserve to earn much on it.
I also hope this can make another peak for KOF. Maybe someday, KOF can truly become a fighting game that can compare to SF...Of course, I personally like KOF better.
