to be fair, the SSDs in the new MBPs and also in the last 2 generations have been among the best of their class when released. They went with PCIE really early and the new MBPs SSDs reach insane (sequential speeds). Also i believe the RAM is limited to 16GB by Intel for some reason (maybe chipset or CPUs), not by Apple.
