The 60 fps RAW files are squashed and need to be stretched by 167% for correct aspect ratio.  This causes some loss of detail as shown below.

Can this be improved?  The RAW streched image is better than canons 1280 60 fps but not as good as pure raw at 1280x740.
See below image:

We don't know how to change sensor sampling modes yet.

(well, I'm pretty sure g3gg0 will find out at some point :P )

I tested the 1280x540 stretched option today and yeah it's pretty much unusable, it looks like it's been youtube compressed. 1120x640 60p ran for about 38 seconds on the 1066x card which isn't a bad length for slo-mo. With a bit of upscaling in post it should look ok, unfortunately it was missing from todays build so I haven't been able to test it. The card slot to SSD option should give us the extra horsepower for sustained 720p 60p.
