Route 66 has been postponed until 2021, and it will have the Dinoco Truck in Catastrophe Canyon as it has already the colour scheme for it on the watertower. Studio D has been constructed and will not open in 2020 and is as well postponed until 2021.
So far Avangers is still on schedule to open in 2021 with Hotel New York: Art of Marvel in Q2 2021. However I don't believe that DLP will open any major new attraction or hotel unless they can have full press coverage for it. As we have seen with Ratatouille in EPCOT, the ride is finished but they are waiting for the right moment to actually open it with the best media coverage for it.
It is rumoured that the full price tag announced for the expansion also includes an expansion for Disneyland Parc, most likely Mickey and Minnie's run away railway at the former Beauty and the Beast location. But there is no evidence thus far that supports this. Or the rumoured expansion at Indy.
