There are pieces to the puzzle. Announcement of MSEP comes on heels of some rumored confidence in ROL opening Sept/Oct. Makes sense to me with 2 added nighttime entertainment offerings that will be draws this fall (ROL and SWS) that timing is right to phase out MSEP as there is the Special Event parades in MK. However it doesn't make sense to continue with that strategy once the Special Event parades are gone. Thus I favor the thought of a new parade coming early 2017.
Paris factors in this, no? Did DL Paris have a night time parade? When is their anniversary celebration?
I expect an announcement of PTN going to Paris with a follow-up announcement about WDW parade offering for Spring 2017. They won't announce WDW before PTN Paris announcement. They need to build the excitement and anticipation
