New firmware for FZ150 can do it?

Questions for the tekkies...

What can a new firmware for the FZ150 improve compared to version 1.0?

Seeing the test shots between 0.2 and 1.0, everybody could see the improvement, what else can it be improve in quality and in performances.

Pana wrote that they cannot do anything for "UMS-I" and the Sandisk 45MB card, so the firmware cannot decrease buffer time..

Any idea about what else can be better in new fw?
