Anime News Network did an interview with Daisuke Ishiwatari and Toshimichi Mori revealing some interesting bits, one particularly hinting at a finale to the Guilty Gear games by the creator himself.
"What are you two working on these days, after you get home?
Mori : BlazBlue got much bigger than I expected. If I could, I'd like to do a bunch of spinoffs and work with BlazBlue more, but the problem is that if BlazBlue: Continuum Shift doesn't sell, I can't do anything before that. So if the fans would like to see more, please support the BlazBlue franchise. I'll be really grateful.
Ishiwatari: I'm still working on several projects I can't talk about at the moment, but I can say that I plan on eventually concluding the Guilty Gear series, so please look forward to that."
The first part of the interview does the "Americans do this, while the Japanese do that!" routine, noting that the two men see FPSs being quite popular in the U.S., but it all came full circle in the end:
"...Would you make an anime-style FPS?
Ishiwatari: I can't tell you!
Mori: This is my personal opinion, but I don't really think there's a boundary between fans of BlazBlue in America or Japan, I love all of them equally, so I will continue to do my best to release the best games possible."
Mr. Ishiwatari also seems to fancy Wesley Snipes' stunts as well as Metallica while Mr. Mori likes ...the Star Wars prequels(?!).
Never would have guessed.
