Q: Any idea when Aperture 3 RAW driver is coming out for Canon G16?

Sorry, only Apple will know that, Rob; and even if we knew, nobody would be allowed to post it here, before the raw support has been released.

Keep checking this link.  Apple - Aperture - Technical Specifications - RAW Support

I'm waiting for the Aperture update so I can start playing with my pics.

I can understand, that you are eager to try your new camera - try Adobe's DNG converter, while you are waiting - http://www.adobe.com/support/downloads/product.jsp?product=106&platform=Macintos h

or shoot rwa&jpeg and set the Import panel to import raw&jpeg, with the jpeg as original. YOu can change that later, when the raw support has been released, and use the raw files you imported.
