I do agree that it's extremely confusing that Path of the Trailblazer would debut in a new storyline, especially when 00 is already proceeding apace in the Z storyline. I think that and Demonbane are the two biggest reasons to suspect its falsehood, along with the confusion in the initial announcements. That said, I'm not reaching a conclusion one way or the other until I see some scans.

No Getter, no Kabuto Kouji and no UC Gundam. Plus, this game will have some form of DLC. I don't know about you but I have mixed feeling for this.
