Some things about cards and the 70D build:
I have one 70D and one EOS M right now, if developers want to test anything specially with the 70D (danne is doing some AWESOME work updating the EOS M already), count with me.
About the cards: The fastest i’ve been able to get on the 70D was about 70mb/s with an Adata v90 128Gb UHS-II with fixed overclock on 160Mhz:

Something i just thought: in ML since we have the info on focal distance used, aperture, depth of field and others, do we have the info on the rotation of the STM (or FTM USM) ring? If yes, would it be possible to use that info to replicate the RF control ring (change ISO, WB, etc)?
