They did specify [0] that it was intermediate frames they were generating back when the 1st version frame generation was announced with DLSS 3, which does translate to interpolation. It's only natural to assume MFG is the same, just with more than a single intermediate frame being generated.
It is also just plain unsound to think that it'd not be interpolation - extrapolating frames into the future means inevitably that future not coming to be, and there being serious artifacts every couple frames. This is just nonsense.
I checked through (the autogenerated subtitles of) the entire keynote as well, zero mentions there either. I did catch Linus from Linus Tech Tips saying "extrapolation" in his coverage [1], but that was clearly meant colloquially. Maybe that's where OP was coming from?
I will give you that they seem to intentionally avoid the word interpolation, and it is reasonable to think then that they'd avoid the word extrapolation too. But then, that's why I asked the person above. If they can point out where on that page I should look for a paragraph that supports what they were saying, not with a literal mention of the word but otherwise, it would be good to know.
Reflex 2 seems to be asynchronous projection [0]. How the two techs come together when both are enabled, I'm not quite sure how to fit together in my head, but clearly it works fine at least. Hopefully there will be more coverage about these later.
