Yeah they just gave animations to most old pokemons from those ive seen, they atleasty fixed some of those who had bad sprites, Pidgey, Migthyena.
Well, basically all the large fan sites received a letter from Nintendo saying that they're infringing copyright by having those images on their sites. You can read the full letter here:
As a side note, a little earlier a friend of mine told me that 4chan's Pokemon board are talking about how they created the letter and are trolling fan sites, Serebii being one of them.
Well actually it looks as if the email was faked.
