I haven't kept abreast of the rumor mill, but last I read it seemed that the APS-H sensor wasn't going to go away as rumor was Canon was going to add that to the new 7D MKII/X. Who the phug knows?? They've been dragging their feet, so I kinda doubt they'll even come out with a 7D successor. The 70D doesn't count IMHO!
Up to 12fps on the G16 is impressive. The aperture is pretty damn nice to boot!
