Maybe not in this short, but I still believe it's possible that there's another Eeveelution, maybe it won't happen, but it's still possible in my mind.

I think it is very possible, that Sylveon was created first, and they chose not to include a 2nd Eeveelution at first, but then someone created a design, and they decided to include said Pokemon into the games, so there wouldn't have been enough time for merchandise to be made of the 2nd one (just Sylveon), at least one that would be revealed right now, with the other Eeveelutions, since I'm sure merchandise of Slyveon was in production before the Pokemon was revealed to us. And another reason why Slyveon would be the only one in the short, is also because of the two, Slyveon is the most "cute/marketable" and they just want to devote the short solely to Slyveon, then if there is another Eeveelution, they might make it an important Pokemon in the X and Y anime.
Misinterpreting my posts is not your fault, negative repping me, and getting very sensitive about my posts because you misinterpreted my posts however is your fault. Think really hard, before negative repping or making a big deal about my posts. I don't appreciate being negative repped for reasons that are a result of misinterpreting my posts.
