Activision said they do not expect a new Bungie title for the 2011 year. However, they are very serious about the new IP Bungie is developing and consider it to have "tremendous long term potential." They also see it as a driver for key strategic growth initiatives. I suppose that is meant to make you feel good as a shareholder.
While no details on the Bungie game are expected any time soon, Activision did mention they are planning new released for franchises like Spider-Man, Bakugan, Cabelas and Family Guy. It's been a while since the last Family Guy game. Let's hope this new one will be better than the last one, shall we?
