I think it's more like "indefinitely on hold". I am not much for speculation, but I am for past history. Reflections has a tail wind of some 30 permits filed in April for construction including the guard house, bus stop, roads, 6 buildings and a few other odds and ends. These would have pointed to them continuing to go forward.
However, lets rollback the clock 20 years. POP century was well under way with Phase 2 being build across the lake. Phase 2 was further along then Reflections is now - it had in fact gone vertical and the outside building was mostly intact. That was when 9/11 happened and tourism to Florida slumped. It's a very close parallel to what is happening right now, and we can in many ways assume that there will be similar slumps (although even longer and more pronounced than 9/11).
Given that those buildings say there for almost a decade before Disney came up with AoA to move in there, it would be reasonable to draw a similar conclusion for Reflections. Just like AoA, they have the land, it's earmarked, it's been cleared and some work has been done. They will likely resurrect it at some point, but last as likely as with AoA, they they will likely re-address it and open it up to re-imagining. After all, in 3 years or 5 years when they bring it back, Bob Iger will be well out, Chapek will be more in control, and who knows what the Resorts division will look like.
