I guess Honda's kind of answered my question for me. They've just annouced that the next NSX will include SH-AWD.

Acura Says NSX Replacement May Be All-Wheel Drive
Date Posted 08-16-2005
TOKYO — The successor to the Acura NSX, which arrives in 2008, may feature Honda's high-performance all-wheel-drive system.
"Of course, we're thinking" about combining all-wheel drive with the V10, Takeo Fukui, Honda's president, told Automotive News. "The SH-AWD is Honda's core technology, and using this well is the next step."
SH-AWD, short for Super Handling All-Wheel Drive, is the first system of its kind to distribute optimum torque between the front and rear wheels and between the left and right rear wheels. Honda has said it intends to use the system on future high-performance Acuras, the brand's upscale models.
Honda has said the NSX successor will not be front-wheel drive. Production of the current rear-drive, midengine two-seater is scheduled to stop at the end of 2005.
What this means to you: High-performance all-wheel drive sounds like the perfect match for Honda's V10 engine in the next-generation NSX.
