So, basically I have a source involved with TPCI, mainly the anime. While the episodes are animated in Japan, there is some crossover with the English branch, and the dub actually receives information about upcoming episodes in-development ahead of time, for various promotional and planning purposes.

Anyway, my source has provided me with a few upcoming episode titles (these are not the final dub titles probably, but rather the Japanese titles translated) and rough summaries which he came upon, set to air in the first part of 2015.

XY61: "Rhyhorn Joins in Too!? The Earthshaking Performance!!"
Serena's Rhyhorn watches Fennekin and Pancham practice for the next Pokemon Showcase, and violently begins to interrupt it. Rhyhorn wants to perform as well it seems, so Serena begins practicing a new routine showcasing her riding skills.
