Thank you (and
@Lee and a number of others) for the information you can share.
From what we have seen, this is my best guess as to the plans as they now stand....
Phase 1 is Toy Story Land plus potentially some other small stuff (Villains show in the BatB theater, replacement for VOTLM). Sounds like this may be (relatively) "fast tracked" to be finished first, perhaps in the 2017 timeframe
Infrastructure (parking decks) will probably worked on to be completed in the 2017-18 timeframe
Phase 2 is Star Wars, with maybe a somewhat accelerated schedule than previously, completed in the 2019-20 timeframe.
Phase 3 is additional Pixar stuff, likely replacing LMA/Catastrophe Canyon and maybe part of the SoA. Strong rumors about Cars being part of that, maybe some other Pixar stuff. Probably completed in the 2021 timeframe. It seems the exact roster of this development is not finalized, but funding is there.
Phase 1-3 (and infrastructure) were the components of the $2.8B approval going towards DHS. Phase 3 info probably won't be officially announced until D23 2017 (which will probably have more specifics on Star Wars at that point).
Phase 4 is blue sky stuff being developed, not currently funded/approved. So... let's not get our hopes up.
I guess if there is some "other" IP being added (e.g. GotG, more Muppets, other Disney animated films, Indiana Jones) that it would be part of Phase 3 or hoped for in Phase 4.
