I'm going to be so pressed if Yveltal really is another Dragon-type. Like, I thought it would be a Flying-type given its avian appearance. I'm really tired of the Dragon-type hype. :x
Yeah I agree, I'm sort of sick of the cover legendaries always being Dragon-types. Unfortunately I think it's pretty unlikely that Xerneas won't be a Dragon-type, then, but only time can tell. Dragon/Psychic or Dragon/Grass for Xerneas wouldn't be too bad though I hope it's not Dragon/Steel.
