The Xbox (and PC) exclusive Titanfall is set for release in March next year, but EA seem sure that the game will spawn a sequel and won't rule out the potential of releasing it on multiple formats.
During a conference (transcribed by Seeking Alpha) EA's Blake Jorgensen had the following to say:
"I'm sure that there will be future Titanfalls at some point that may be on multiple product platforms. [I] don't know, that's up to the teams that are going through that now, but at the end of the day, we're excited about this Titanfall and we think it will be a big title and it will be great for Xbox One."
