I am willing to buy the new G12 but Canon did not come up with a new underwater housing for it.
(There is an underwater housing for G11 - the WP-DC34)
Here is the tricky part...
I have emailed the canon email support team - they werent clear but they said WP-dc34 is also compatible w/ G 12...
However, the G12 has a new dial on the front

I asked they said there is a way for using the dial without touching the dial ?!?! : )
anybody have any idea?
