Do you know something we don't or are you just speculating? From what I've read the G1 sensor has been redesigned for the GH1
Panasonic's intention from the beginning was to add video to the G1. They've in fact announced a video version of the G1 at the same time as G1. It is a new design, but more of an evolution then completely from scratch.
As for judging low-light performance, they should be fairly similar. Fundamentally, the factors that contribute to better ISO performance such as pixel-density and the size of the photosites are identical to the G1. Also, the 60fps EVF capability of the G1 indicates that there is some inherit video capability in that sensor. We may seem some improvement due to the dual-Venus processor and improved noise-reduction algorithms, but for stills we shouldn't expect any big improvement over the G1.
