After chatting to a cast member online this morning, they confirmed that NONE of the Disney areas will be accessible, even Shanghai Village which was reportedly meant to open on May 19th, until the 16th June opening date:
I also asked if the metro line would be open, and was told that it wouldn't.We are going to open on June 16, 2016, and including all of the area, sorry about your timing.

All Shanghai Disneyland resort is going to open on June 16, including Disneytown and other area.
This is disappointing, as I was hoping to at least get a glimpse of Disneytown, Shanghai Village or at least the lake area at the end of May/early June.
