Infiniti G35 Hybrid

The Infiniti G35 is a great car, and the news that Nissan plans a hybrid version of it is good news indeed. Lithium-ion batteries and everything, I read excitedly, thinking this car could maybe be some kind of plugin-hybrid that could travel at least small distances on battery power alone. Unfortunately, Nissan's press release states the following:

The dynamic characteristics of the clutches are as follows: Idle-stop: The battery is used to power the motor to save on fuel.
Regular driving: The engine is used to power the motor as well as regenerate the battery.
Acceleration: Both the engine and battery (power assist) is used to power the motor to achieve smooth acceleration. Deceleration: Energy from braking is conserved and re-routed back to regenerate the battery.

In other words, the G35 Hybrid will be just another Toyota Hybrid or Lexus GS450h, with slightly better fuel economy as opposed to a regular petrol car, but that's it. Why does Nissan aim so low with a car that's not supposed to be on sale until 2010? If this is all I want I could just go ahead and buy myself a BMW 330d, with start/stop technology and regeneration of battery while braking.
