The back dial will eventually be absored by a touchscreen gesture(s). It's the next logical step.
I don't think this will replace the back dial, it's much faster to change settings with this and a top lcd - and we'll have to see how the touchscreen performs with cold, sweaty or dirty hands, gloves or a screen protection above it.
burst rate on 60d is double that of the 650d in raw ,1/8000 shutter , 250 sync speed, finer iso settings. weather sealing. and it does not say rebel on the camera.
Thanks for reminding me - I'm always taking these for granted an am using all of these (except jpeg) a lot, so anything below a xxd would be indeed a no-go for me - and this for a relatively minor added $$$. For the record, even the 5d3 only has 1/200 x-sync, though it only matters for 2nd curtain or else you'd use hss.
