Now that's news to end a weekend on. Excellent. I like how cryptic he was about the when and where, which leaves open the possibility that may be very soon indeed if some rumors prove to be true. But I'd honestly not been holding my breath even though I desperately wanted this to be the case and now I can rest easy.
Now save Donofrio as Wilson Fisk and all is once again right again in the MCU as far as I'm concerned. (And yes, I know that's also a particularly viable possibility in light of Hawkeye on D+. Still won't believe it until I see it with my own eyes or we get comments like this to that effect.)
