Still keeping my hopes up for a Grass/Fire or Water/Fire type mon for Gen 6 Gary. I think if we got either of those types with a decent stat spread and moveset it could really help to get fire types back on track as both those types could potentially handle rain. Grass/Fire could be an incredible chlorophyll sweeper with something like Growth/Giga Drain/Flamethrower/coverage, akin to venusaur except with a stab AND sun boost for the fire type attack and the ability to run HP Ice. Water/Fire could also be interesting as it could potentially work well as an antiweather mon, being able to take advantage of sun boosted or rain boosted stabs depending on the situation.
The existance of scald makes me feel that a water/fire type would be more likely, simply because the concept is already layed out. Whereas everytime I think of a grass/fire I think of moses and the burning bush :S and I have no idea how that would translate into a pokemon. They've done crazier stuff though.
