Despite the loss of Itagaki, Team Ninja is working on three new action titles that will be revealed at next months Tokyo game Show: http://xbox360.ign.com/articles/907/907295p1.html
As for the new titles, I would say: the next DOA(either DOA 5 or DOA Extreme 3), another classic remake(such as Tecmo Bowl or Rygar) and a completely new IP. Since the newest Ninja Gaiden just came out I wouldn't put much stock in them announcing NG 3 just yet. So what do you guys think the titles will be?
