I'm pretty happy about what the trailer has to reveal. The fact they already named the Starters in every language (Feunnec or Fennekin in french, which is a portmanteau of Feu (Fire) and Fennec) is a bit of a surprise though. Also, one thing I'll finally be able to access in Pokémon since Pokémon Platinum : WI-FI !! Having a router that doesn't let me go on Wi-Fi with DS games is quite the pain, and the fact these new games are coming to life on the 3DS means I'll finally be able to go over there ! :D
Now my only true fear is having Fennekin's final evolution becoming a Fire/Fighting type Pokémon, yet again. But I'm pretty sure Game Freak won't do that : using this type combination for the fourth time in a row on a starter would be just dumb at this point.
