IMHO it will come back. Disney uses special events to drive attendance in low seasons. Just like running races during the school year, Halloween parties in the Fall, F+W was used to fill other gaps raising revenue from event tickets, hotels and park admission and other side streams.
DLR is a lot more than AP only park and has fluctuations in its attendance just like WDW does.
We probably won't get any official announcement until later this year when people have already reserved thier high rate holiday visits.
