With six or seven episodes left until the end of XYZ(depending on whether the team flare ending counts as one episode rather than 2), and this development, since we have yet to know a date in 2017 when the anime's move takes effect in full, if the move is slated for the week of January 7th, I wonder if either the XYZ finale, or even worse, the end of Team Flare, will be skipped due to 5 Saturdays remaining until 2017, when Disney XD is slated to take the airing reins from CN, as you already know...
^ If so, I wonder if it will move to DVD and/or Netflix in the same vein as Mewtwo Returns(aired in Japan as normal, but moved to DVD in the USA). If it moves to Netflix, then it's official: The last of Team Flare will get the same treatment as the final season of Star Wars: The Clone Wars(CGI)(in a sense, as any show that moves to Netflix-only to end an arc or series means "too bad: if you can't afford to pay subscription fees for Netflix, you'll miss out on the conclusion of the arc in question")...
^ I feel the sorrow of those that prefer to watch it for free, but can't due to such "wind-down decision-making"...
^ Either that, or maybe CN will double the half-hour slot of pokemon for weeks 2-3 of December, then marathon mode on Christmas Eve, followed by the final two eps before maybe signing out for the night to Adult Swim(unless Santa's arrival down the chimney at that time means a total sign off for the night, indicated by a still-frame spectrum color screen that holds until next morning)...
^ However, if they don't double up the half-hour to full-hour of new episodes of pokemon next week(on December 10th), I just hope that Disney XD picks them up on the marathon before M19 airs, so we don't have to worry about crunch time decisions involving dropping some episodes to the "Lost Episode" bin...
^ ...just so that people are not disappointed by the loss of one or more episodes...
