that the car I ordered will turn out to be a new 2009 with DFI! No more allocations for 2008s. The plants close down in July, production starts up in August, and delivery of my cay is now set for Sept. I'll miss the Summer, but Fall in NE is great. My dealer says he's sure all the Porsche sports cars will have DFI in '09, meaning the Cayenne probably won't.
Inquiring minds have wanted to know. Now that I've passed on the news, I'll probably turn out to be totally wrong in about a week or so.

DFI
Direct Fuel Injection (DFI), is a new technology that Porsche states can cut fuel consumption by up to 15 percent, while increasing power by up to 13 percent. DFI cuts emissions by warming up the catalytic converter more quickly, and ensures a sharper throttle response. Better for your right foot - and the planet, then.
DFI allows much more precise measurement of fuel supply and injection at pressures up to 120 bar; it has numerous combustion modes, with different cycles for cold-starting, low-speed driving and performance driving.
As the name suggests, DFI injects fuel directly into the individual combustion chambers, instead of the intake manifold. The injector valves have an electromagnetic mechanism that controls each injection with astonishing precision, while a high-pressure pump provides the necessary pressure—up to 1,740 psi—to accompany the rapid fire of the fuel injection.
Precise geometry of the injector’s position and its spray pattern is a key factor in helping to improve power, torque and emissions of the engines. The specific placement of the fuel as it enters each chamber creates a swirl that improves the air/fuel mixture, and therefore the overall combustion process.
At engine speeds up to 3500 rpm, a double-injection process is used. In this mode, the required fuel volume is delivered in two successive injections per working stroke. The resulting benefits include faster catalyst warm-up and increased torque in the upper load range.
By forming the air/fuel mix directly in the combustion chamber, DFI contributes to engine cooling. As a result, it is possible to increase the compression ratio and with it the power and efficiency of the engine.
The direct injection process is continuously adjusted. The engine management system reads changes to throttle inputs and performance requirements and, as you drive, the air/fuel mix is monitored and adapted as required. Oxygen sensor circuits within the exhaust system provide accurate emissions control.

So you ordered a 997 then as the Cayman will not get DFI until MY 2010.

The Cayenne already has DFI, I think your dealer may have just told you something you wanted to hear.

Thats what I am hearing. You will be able to order mid 2009 for the 2010 model delivery. Also expecting the facelift that everybody is talking about (sort of) and the PDK transmission. Forget about waiting for that, just get what you want now.
i bet all the PCM and audio/phone/electronics-related updates on that 911 press release will be in the '09 caymans this fall as well.
maybe they wait a 1/2 year to a year before upgrading the mechanicals and the front and tail ends aesthetically, but all that interior stuff that's shared between models will be there in a few months.
