Based on what's been stated in public, it's unlikely to be powered by DirectML, which is a good thing. If it were ML-based, it'd be just as bad as DLSS.
They haven't even stated how they'll be doing it, which means they're certainly not in a position to know how long it's going to take before it's ready for release.
You're not going to speed anything along by posting a question in a user forum.
