Venture Beat is reporting that Darkstalkers 4 might be in development. It's just a rumor for now, but their source is the same person who gave them information about Resident Evil 6 which turned out to be true when that game was later revealed.
In January, we posted a rumor citing a reliable inside source at Capcom who told us Resident Evil 6 was coming. The game would allegedly feature both Chris Redfield and Leon S. Kennedy as the main protaganists, as well as a happy mix between classic small-town survival horror and the franchise’s more recent action-oriented gameplay. Officially, PR told us, “Capcom has made no announcements.”
Shortly thereafter, Capcom released the world debut trailer for Resident Evil 6, confirming our source’s information.
Now our same inside source is telling us that Darkstalkers 4 has been in the works since last year, with Street Fighter IV and Street Fighter X Tekken producer Yoshinori Ono at the helm. The unannounced fighter would use a modified version of the SF X Tekken engine, which itself is modified off of the Street Fighter IV engine. Principal development on SF X Tekken was said to be complete towards the end of 2011, which is when Ono supposedly shifted his attention to Darkstalkers.
