Oh how I'd give all my life savings for a Breath of Fire character in a Versus Capcom game. I remember how I made an account on a chat site just to try and ask a question to the main director guy(Niitsama or something like that) about the possibility of a Breath of Fire character in Tatsunoko vs Capcom during some sort of Q&A Livestream. To think I actually got answered that day.

Find
Unity Events 01/20/10 02:00PM among the videos then go near the end of that video(around 38:30) to where they say they have enough time for one more question.
I can't believe I actually found the video.
I would like to think there might be some hope for BoF characters, since BoF3 characters did appear in the Crossover Comic between Sega and Capcom and Ryu actually appeared in the Top 10/15/20 MvC3 votes(can't remember which, although I think Ryu was either 9 or 14. Nina may have been 19 if Top 20) , but I still do not see much hope, especially after BoF6.
Also, why haven't Sega and Capcom gotten together for Sega Vs. Capcom yet? Especially with how buddy buddy they've been with each other lately. Also the fact that it could potentially help bring attention to Sega's Non-Sonic franchises.
