It was mentioned in the last Round Table without any date estimate. It sounded like progress was being made, but not something Curt was that involved with so he didn't say much.
My understanding is MMP is presently shuffling around their whole production schedule (not just ASL, everything MMP) because the tariffs have made their planned move to Chinese production untenable for the present. Prioritizing lower cost titles to minimize the price delta between planned Chinese production and higher cost US production (though they did specifically say that didn't mean exclusively only smaller/lower cost titles). So I suspect a lot about this year's production schedule is up in the air right now. I got the vibe that SASL3 was still in development/play-test and presumably all that continues regardless of tariff planning.
That's me just reading the tea leaves from the little said so far. I'd really love an update from the horse's mouth! Looking forward to SASL3 whenever it comes!
