I just found out about this. (Or if your from the future, I already knew about this =P)
Oh and just in case you didn't know, this is from Pokemon Omega Ruby and Alpha Sapphire.
I don't know about you, but Mega Metagross looks AWESOME!! I can't wait to see what Mega Salamence looks like....They have to have him too.
It seems like it's contest related. More will be revealed next month.
Here is a quote from Serebii.
"Various forms of Pikachu appear to be related to the contests. Madam Pikachu & Hard Rock Pikachu on the first image, and Idol Pikachu, Doctor Pikachu and Masked Pikachu on the second. It states that more will be revealed on this in the issue next month. It also confirms that Pokémon Amie returns."
I like them all. I hope they have sunglasses...Uh, AHEM, anyway, I really hope that Pikachu isn't the only one you can dress up. I want to dress up a Plusle...Or Minun.
Wouldn't it be cool if you could dress up all 719 pokemon?
Also, here are some other scans.
The new Pokedex looks like the original Gameboy Advance.
Roxanne looks even hotter this time.
