They haven't updated those predictions publicly in a little while. Definitely a huge setback from Rolls-Royce dropping out, and putting together the coalition that's developing the Symphony engine. Latest I've seen on Twitter is Blake Scholl stating the first full-size engine core should be making thrust by end of 2025.

I'm guessing rollout realistically is more like 2029-2030... but even that is a tall order. Unless, of course, they're a lot farther ahead on Overture development generally than they've revealed.
