I'm seeing 15" with a 6G optical bay, but nothing from 17" users. Can anyone confirm a 17" with two 6G ports?
I just got my maxed out 17" hi-res anti-glare in yesterday afternoon. Happy to report both ports are 6G.

My machine appears to be fresh off the assembly line too:
Group1: MacBook
Group2: Pro
Generation: 83
ModelCode:
Model introduced: 2011
Production year: 2011
Production week: 19 (May)
Family name: Become a pro user to see this information. (sorry)
Screen size: 17 inch
Screen resolution: 1920x1200 pixels
Colour: Aluminium
Factory: C0 (Quanta Computer (Susidiary = Tech Com))
I've got an OWC EXTREME 6G 120GB SSD on its way (hopefully early next week) along with a data doubler and will be putting the stock 7200rpm 500GB drive in the Optibay as a data storage drive and housing the superdrive in an external case.
Loving the machine thus far - this replaces my aging 5-yr old original MBP. Still rocking my early 2008 Mac Pro for desktop 3D work.
