This looks real, the aesthetics on the titles and the names makes a lot of sense.

i bet they are.

Yeah, I've checked it in the OHIM and it's definitely there. New gen then? I'm excited as fuck.

Pokémon S&M though doesn't sound right xDDDD.

Huh, well... That does look rather legit. That could be a good way to celebrate pokemon's 20th anniversary.

A new gen already? Too soon, man. I was expecting something different. This looks legit, but I will wait for tomorrow's Direct.

That would be a nice impulse to the 3DS sales, yeah. Well, I expect them to be 3DS games, but you never know.

Here come Pokémon Rainbow

Now that I think about it, the codename "Rainbow" for a game called Sun and Moon sounds... legit. 

Looks legit, guess we'll find out tomorrow.
