My guess is that the various processor SKUs we are seeing right now is due to the binning process. As their yields improve, we may see Apple streamline their laptop offerings by making the better processor options available for cheaper. But I don’t expect very significant updates to it in the near term. Pro Mac users have signalled that they are perfectly fine with a conventional laptop form factor with a powerful processor, sustained performance, long battery life, magsafe and tons of ports. As long as Apple doesn’t screw up the OS experience, they are pretty much safe.
