Wow! I totally fooled by this the first time I saw this CoroCoro image. xD
Yeah, it's very well done... the screenshots just look very much like how it would actually look like if they were announced. But the problem is... the screenshots are much more like the trailer more than anything, just replaced with the 3D designs of those Pokémon.
I'm just shocked that this is actually confirmed to be fake, 'cause it looks too real. ;-;
Whoever designed this probably put so much time and effort to complete this to perfection. Even I would have trouble making something as amazing as that to be spread as a rumor. xD
But yeah... it's too early for any leaks of CoroCoro yet, most of the leaks come during 10th or later in the month.
But other than that... about those Pokémon, no matter if they're fake or not, I still like the designs of those Pokémon. ^^
