Edit: to their credit, that shit was sitting at 30 plus seconds per match, so it's not like they aren't optimizing. 20 seconds isn't that long either. But it's certainly not blazing fast unless the build I posted is wrong.
It was actually going up to 65 seconds.
Dead or Alive 5's load times at E32012 were also around 20-30 seconds. But the difference is, they managed to shave off 90% of the load times from their preview build to release.
