The developers of Titanfall have revealed that a special a special announcement is scheduled for tomorrow. At this stage of development, we cannot help but think it to be anything other than announcing that the game will end up as a cross-platform title. Microsoft had originally announced Titanfall to be an Xbox One exclusive, but seeing Major Nelson's most recent comment, it might not be so. Well, technically, it might still be an exclusive, albeit a "timed" one.
Here's the Major's reply when asked about the exclusivity of the Source Engine powered title:
"As far as being an exclusive that's really a question for Titanfall - I'm not worried about it though."
To confirm the same, we will have to wait for the official announcement. Check back tomorrow for more coverage.
