What is the 15th season of pokemon about? New foes, new friends, and dozens of never-before-seen Pokémon await Ash and Pikachu in Pokémon: BW Rival Destinies, the new season of the Pokémon animated series. As Ash and his friends continue to explore the Unova region, he’ll find himself up against the ultimate battle challenge: Alder, the Champion Master of Unova! His friends also face their own trials, one fighting for the right to continue her travels, another confronting a returning challenge from the past—and all three of them must team up to save an island from the clashing forces of three powerful and mysterious Legendary Pokémon! - - -

My ten bucks are on that the 15th season would start with the selfish Gothita episode or the Driftveil gym battle episode. The selfish Gothita episode would make more sense since that the Sawsbuck episode would mark the 52nd episode that has aired in the series. That being since that we get a new season after the 52nd episode of the previous season airs. I mean that has been the case ever since 4Kids stopped ruining the anime. Though the Driftveil Gym might be the better choice if they want to air the two part Kami episodes in the 14th season. But hey , It might be the Bianca vs Elesa episode since we have yet to hear an air date yet.

Besides the point , It seems to me that it's certain that the 15th season would be somethime in the upcoming year that starts in 1 hour and 11 minuets from the time I post this.
