One bad thing about 46MP is more than 5fps seems VERY unlikely. 38MP would be plenty enough and if it could do 5fps at 46MP it could do 6fps at 38MP. In all honesty, noticing 38MP vs 46MP is a LOT tougher than noticing 5fps vs 6fps. OK sure they can brag it's a fully 10MP above the D800, but making it speedy enough for action/wildlife (which the 38MP reach would help with too) would make FAR more practical sense to me. Sure some pure studio and landscape would take the 46MP, but they'd be making it a lot less well-rounded, making it more specialized and likely higher cost, for, IMO, not THAT much practical benefit.
