Time for new starter types?

I think it's time that we had new starter types for the games. I mean, Fire/Water/Grass is getting old now, especially considering they can't come up with a unique type combination for Fire, seeing as they've gone with Fire/Fighting for three straight generations (III, IV, V). Personally, I remember when people thought there would be Psychic/Dark/Fighting starters, and I wouldn't mind that, although Dark has an advantage as it is immune to Psychic attacks rather than resistant. What do you think, and if you think new types should happen, what combination?
