With the falling economy in Japan (or rather the fear of, Japanese analysts expect much worse than it goes all the time), the price is the most important.
So what I think they need, is a very long lasting game (ala MKWii, SSBB or Wii Fit), that's Japan centered. Final Fantasy fills this up fairly well, and if Versus turns out well, they have what they want.
The market in Japan is all about momentum. At the current moment, Ps3 hasn't been able to catch the momentum for 2 weeks in a row. What they need is to keep the momentum going for at least a month. That would improve them a lot for the long run. The problem - Nintendo won't let them.
