PTN is not really "Disneyland's parade", it's about 90% replica form Hong Kong's PTN. So it's a hand-me-down design already (which many people at the time of it's announcement were upset with).
WDW
is getting a new parade that we know is scheduled for it's 50th, that hard date is very important in determining what is done in the interim years. Any night parade that is brought to WDW has a known limited time slot. It's relatively unlikely that a genuinely new night parade would be built for WDW to be replaced when the 50th rolls around; whereas a copied or transplanted parade is easier done.
There are multiple options dealing with what would be done within the context of MSEP's move to Disneyland. And also the relationship of likely night
AND day parades for WDW's 50th.
- WDW goes sans night parade until it's 50th.
- WDW receives refurbed/coppied version of MSEP after Disneyland's run that plays until it's 50th.
- WDW receives refurbed/coppied version of some other night parade that plays until it's 50th. (MSEP is either retired or stays at Disneyland)
- WDW receives new night parade prior to it's 50th; no new night parade for it's 50th.

From everything I've heard out of reliable sources WDW absolutely does not want to be without a night parade for more than 9-12 months. Loosing MSEP in early October is not ideal but still reasonably timed with many nights taken over by parties then the Christmas parade running during the day until 2017 and January/February being a "slow" season. It get's dodgy when Spring breaks start (but with Easter pretty late in 2017 they might luck out with later than typical vacations).
My semi-educated guess is WDW will have a hand-me-down/copied parade starting sometime around late March. I'd give it about 50/50 that it's PTN vs some other night parade.
