speaking to my OPC about ordering one and was told that possibly the initial line up would consist of a base model (c2) and an 's' model with more power (much the same as the current boxster line up)
I've heard rumours that there will be no Turbo or GT2/GT3 for the 997 lineup. The 998 will be out around 2 years after the 997 and will be a lot different.
