Under other circumstances I would say yes, but we
still don't have any information about Newtwo.
I also find it odd that Corocoro haven't shown all of the E3 Pokémon yet, even if they are on the Japanese site. If this are indeed the only scans, then hoo boy, we will have happy fun recapping time every month until the release, and it won't be just Smash.
The former was started by Hirobyte who stated Sylveon and Xerneas were going to be Pure Fairy and Yveltal was going to be Dark/Flying. He also stated that Clefairy will be Fairy-type. He also also apparently implied that one of the Gen 4 Pokémon will get an evolution in a forum according to somebody on 4chan, but I don't know how accurate that is.
The latter part was stated by a person who had seen the beta that contacted to WPM(Pokébeach's owner). Here is the information:
1
2
3
The last one were the name leaks of the previous Corocoro Pokémon, which turned out to be largely correct.
Both groups have stated that the other is full of crap, even though there is absolutely no contradiction between them nor they have the absolutely same information, except for Sylveon's type.
