Gen 1: Charmander/Charmeleon/Charizard=Fire/fire/Fire&Flying (Cool)
Gen 2: Cyndaquil/Quilava/Typhlosion=All Fire. (Good)
Gen 3: Torchic/Combusken/Blaziken=fire/fire&Fighting/Fire&Fighting (something new)
Gen 4: Chimchar/Monferno/Infernape=Fire/Fire&Fighting/Fire&Fighting (we had this last Gen.)
Gen 5: Tepig/Pignite/Emboar=Fire/Fire&fighting/fire&Fighting. (aren't we getting a bit too repetitive?)
Look at the above: We've had fire&Fighting combos for the past three generations! Can you really see Fennekin becoming a Fire/Fighting fox? I, for one, cannot. I believe that Pokemon will make it something we haven't seen before in a starter Pokemon. Also was that a fighting type move Fennekin used in the trailer? No, it looked like a Psychic move.
