Yeah, I counldn't imagine a PDK or DCT in our cars and still being able keep the price down. It would be called a GT-R then I think.
Found some more information on the topic that others might like to see.
What I have been trying to say is: For a S7 the Nissan 370Z's seven speed is pretty crackin':
The 370Z’s 7-speed automatic with Downshift Rev Matching (DRM) and Adaptive Shift Control (ASC) is designed to offer quick, manual-like shifting when operated in manual mode with a target time of 0.5 seconds between shifts. Drivers can use the standard paddle shifters or the shift lever. With optimized torque converter lock-up logic, the 7-speed automatic feels very direct, like a manual transmission. The 7-speed’s wide gear ratios offer improved fuel efficiency (versus a 5-speed automatic), while the Adaptive Shift Control is designed to adjust to the driver’s driving style.
Fuel economy is rated at 19 mpg City/26 mpg Highway for the 7-speed automatic and 18 mpg City/ 26 mpg Highway for the 6-speed manual transmission

In manual mode, the optional 7-speed automatic shifts quickly. Drivers can use the paddles or lever.
The shifts feel direct, like a manual transmission, thanks to what Nissan calls torque converter lock-up logic.
Don't get me wrong, I still think I can shift faster in a manual transmission car however, the numbers would tell me different in a 370Z and my experience is that the Z has one of the best S7 I've driven especially for the price.
It not always how fast you can shift. Sometimes it's if you can shift in a corner or not.
