This is the updated timeline that I heard. Take it with a teaspoon of salt since it's from a friend who spoke with an "insider" (at least I'm being open).
Toy Story Land Fall 2017 (AVATAR Spring 2017 for the three people who care).
Star Wars 2019 (no mention of a season, but it is being coordinated with Disneyland; personally, I'd guess May)
Cars Land 2020
Large scale construction underway south, east, and west in the park by this time next year.
And there is still a project heading down the pipes for MK's 50th.
He also mentioned that Osborne's imminent cancellation was a recent decision (meaning the schedule has been expedited). Again, salt. However, DL traditionally avoids large-scale construction during their decennial celebrations and is now planning to break that rule, suggesting an acceleration in pace.
