Both Panasonic G1 and Panasonic G2 have Four Thirds sized 12.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the G1 and G2 sensor size comparison.
Panasonic G1 and Panasonic G2 have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture.
