I agree. Doing a quick search it seems as the current completion date should be early 2016, so sailing the Alaska in 2017 with either the Magic or a larger Wonder SHOULD be doable, but I would expect Disney to wait until the new canal is actually opened before enlarging the Wonder. Just in case there are unexpected delays. I suppose if they add the ducktail and there are delays in the canal opening, they could always do a repositioning cruise that takes the long way around South America. I would do that cruise if I could get that much time off from work
