True, the SSD inside is a proprietary module, but so was the SSD in the MacBook Air and a couple months after the release there were SSD upgrades from OWC. The ram is completely non-upgradabe because it is soldered to the logic board, but the SSD should be replaceable on the 2.3 GHz model. I doubt apple would change there logic board layout for that model due to the cost. I would wait a few months and there will probably be a storage upgrade soon but don't expect it to be cheep.

Hope this Helps
