The final spec will soon be available for download from http://midi.org
More details can be found in the official announcement of the MMA:

Great contributions Geert. It’s indeed very exciting! I’m happy MIDI is adapting to the newer realities of music playing.
In addition to MPE, the MIDI Capability Inquiry (MIDI-CI) specification [1] just announced as well is another step towards a more pleasant MIDI future for players like me 🙂 Cheers! — Alex / Satri
