Satoshi didn't have a 1MB limit in it. The limit was originally Hal Finney's idea. Both Satoshi and I objected that it wouldn't scale at 1MB. Hal was concerned about a potential DoS attack though, and after discussion, Satoshi agreed. The 1MB limit was there by the time Bitcoin launched.
It would be great if Satoshi would chime in. Maybe if the coin does indeed begin to snap in two?
There is no need for Satoshi to chime in (although if he did reappear I have a list of questions). The first version of the client had no block size limit. The second version of the client had no block size limit. The next 146 commits to the repo had no block size limit. The source code is the proof. The block size limit wasn't added as an anti-spam mechanism until more than 21 months after the genesis block.
