...You know, Greninja licking off his bubbles would actually freak me out more than him using his tongue as a scarf. XD But seriously, I don't know about anyone else, but I like Greninja enough to be disappointed if he weren't real. His "scarf", alongside the stance he's making in the shot, reminds me of Strider Hiryu for some reason.
Of all the new things swirling around Gen Six, I'm likely excited about Fairy Type the most (with Mega Evolution in second, despite the apparent "hate" surrounding it on this site). I'm definitely playing as Serena as well. Comparing the two MCs, it looks as though they spent more time and detail creating Serena than Calem, and it's become apparent she's getting the limelight to show it off (as she's both in the anime and the apparent posterchild for character customization)...that, or the developers knew they designed a winner when they made her. Either way, I haven't liked a female lead this much since Dawn.
I was looking around online....and apparently, some yutz on Reddit claims he has a legitimate copy of Pokemon X (He even has a picture of the box opened with the cartridge showing--complete with the whole "Official Nintendo Seal"). Since I'm terrible at linking to sites right now, I suggest opening up Pokemon X's Board on Gamefaqs--people are starting to take interest over there, and it's where I found the supposed guy talking about it.
Of course, if he's the real deal and goes crazy with the spoilers, the guy's in for some serious legal action from Game Freak/Nintendo.
