The Canon G10 is now in stock and shipping for $499 Calumet via Amazon. I expect that current stock will sell out within the day today.

Update: As expected, the stock at Calumet didn't last long. However, the same Amazon link below will now take you to Amazon where the G10 still lists as in stock, this time at J&R. Let's see how long their stock lasts.

The G10 is also available at B&H, another reseller I can recommend strongly.
