More often than not, its tough to visualize the difference between sensor measurements merely by looking at specs. The graphic below will help provide you a far better sense of the sensor sizes in the SX70 HS and DP1.

As you can plainly see, each of these cameras feature different resolutions and different sensor measurements. The SX70 HS due to its tinier sensor is going to make shooting shallower DOF more difficult and the Canon SX70 HS will resolve greater detail utilizing its extra 15MP. Higher resolution will also make it easier to crop shots way more aggressively. The younger SX70 HS should have a benefit with regard to sensor technology.
