Apparently a slightly edited version of the opening titles has revealed that Ash will be the one catching Noibat. I'm kinda dismayed at that, because that'll be his third Flying-type caught in Kalos. Seriously, are the writers like so obsessed with giving Flying-types to him or something? Or even the fact they're replacing his just released strong Dragon-type with an extremely weak one?
Eevee was also shown in the new opening wearing some dress-up which means Serena will be catching it. I hope they evolve it into a Sylveon because it would look nice with her.
The arc in Diamond & Pearl where Torterra had to change strategies due to gaining weight from evolution really cost him badly, since he ended up getting overshadowed by Infernape towards the end of the series.
I have a feeling Fletchinder and maybe Pikachu will likely have to do a lot of this Gym, especially as Hawlucha will likely become a fall guy again if he got used, just like what happened to him against Ramos.
A discussion about why the dub keeps replacing the Japanese music. Apparently most of the music used in the original Japanese version is owned by Miyazaki Shinji and if the US dubbers try to use the music they have to pay him loads in royalties, so to avoid going through that they make their own music and insert that into the dub instead.
Still, it's incredibly lazy because I was expecting new opening titles and a new title card to accommodate the new short-haired Serena but they decided "no we'll just leave it as it is and not show her new look in the opening until the next season".
