Squenix is doing a DQ press conference this Monday where they will be making a huge announcement of the series. Most speculation is that they are finally going to reveal DQX since its a Wii exclusive and the consoles days are numbered.
Course I imagine some other announcements as well, like a new Joker Monster title and of course some heavy PR for the DQ Anniversary pack that's slated to come out soon. I imagine a few spinoffs as well.
