Titanfall isn't coming to PlayStation 4, but its sequels are likely to, and so are other games from Respawn Entertainment.
Responding to fans on Twitter today, Repawn co-founder Vince Zampella said "of course" the developer will make games for the PS4.
"Just not the first Titanfall," he said, implying sequels are likely to come to Sony consoles.
In a separate tweet, Zampella said Titanfall had always been a Microsoft exclusive at launch, but that the lifetime exclusivity mentioned in EA's financials today is a recent development.
"Always MS exclusive at launch, great partner and focus is good for a startup. EA made a deal for the rest, we only found out recently," he said.
Titanfall is due at the end of March 2014, on PC, Xbox 360 and Xbox One.
