Kotaku.com is reporting through Reuters that Capcom is considering more Wii releases. The quote of interest from Capcom states:
"Up until now, after releasing our PS3 and XBox 360 games, we have brought them to the Wii. Basically, this is the approach we are considering taking."
Despite being a bit 'Engrishy' it's sounding more and more likely that Capcom is going to try and get some of their bigger titles on the Wii after they've hit the more powerful systems.
In somewhat related news, Capcom also announced that they plan to release up to 10 new titles on the iPhone by March 2010.
While the Street Fighter games aren't mentioned in any of these articles, considering it's one of Capcom's biggest franchises, it's likely the series is high up there on their list of titles to port.
