Aces, the 70D's sensor is a bit bigger...20% maybe, someone will quote exactly how much bigger; but that difference might have made for an even larger G1X platform. I think it's big enough as is
As is I'm just thankful for the upgraded lens. The ISO profile of the Mk I was super, with the advancement in processor that should only get better, couple that with the F2 speed and walla a low light machine. It might even give my 6D a run for some money.
