From what I gather on here this is the timelineI wouldn't be surprised. One thing for sure, 2018 is looking like a slow year for new things besides TSL right now. Lots of new this year and tons of new in 2019. I wonder what else could be happening in 2018?????
2017- Avatar land
2019- Caribbean beach and Coronado expansion plus ROE 2.0(?) Maybe SWL late in year
2020- SWL if delayed a bit, RAT, GMR, possible Coco overlay of 3 Cabs
2021- Whatever happens in MK which is likely stitch replacement and if the decide on doing a new e ticket/expansion
I think (assuming SWL is very late in 2019 or just early 2020) 2019 could be more of an in between year. Still seems to be lots of other stuff like central spine revamp at epcot and lots of updates at MK for 50th to make things sparkle. I wish we could have what Tokyo and Hong Kong do and release the long term plans so early.
