I wouldn't mind it becoming an OVA or something like Chronicles. I... actually wouldn't want this to be a full blown animation because the animation quality probably won't be as fabulous as it is in the trailer. Though I suppose it depends on how long they would make it animes that are longer/weekly are usually of a lower quality than those that are less episodes/not weekly releases. Of course there are exceptions on both ends but you never know.
Too lazy to quote, but Cheren's "herdier" is actually a Stoutland. Not sure if anyone pointed that out (I'm way too lazy to look back) but I hope this means that we get to see what is probably going to be a Lillipup evolve throughout the game if Cheren is actually involved (which I would really love but I'm not giving my hopes up considering what kind of promo this is.)
