The tweet, from CEO Vince Zampella, says this:
Tons of things planned for @PlayApex in the future. We are also committed to listening to player feedback.
We are also working on more Titanfall for later in the year (yes, I said the T word). We love being able to experiment in this crazy universe!
Meanwhile, EA’s Andrew Wilson said this:
"While I don't have more to share with the particulars of what we have coming from Titanfall, Respawn are a tremendously creative team. They always anticipated that Apex Legends would be a spectacular game in the battle royale genre, and that they'd use that as a ramp point to deliver a truly creative take on what Titanfall is in a premium context later on in the year."
So a “premium” Titanfall thing is coming, but if it’s not Titanfall 3, what on earth is it? Technically neither men say it’s a game, so it could be anything from an animated TV series to a friggin’ dating sim, we just don’t know. But if it is coming in 2019, then we probably won’t have to wait long to find out: they probably won’t try to drop more Titanfall stuff on us by surprise this year.
