I think the big take away from this, is that it appears there is a conscious effort to expand attraction capacity in the park. Disney seem to hold on to those expansion pads very tightly, now they seem ready to start to use them.
It's a significant change in the last year plus. Unsure if this is the fruits of the my magic plus system, or result of that expenditure winding down. Bottom line, they are spending a lot of money to expand their attraction offerings and their lodging options. Something is giving them the indication that now is the time to do it.
