Erik, right now there is a lot of speculation regarding this issue. Another reason might be the surprising success of the GT3 RS (they need the parts
).
I try to find out more but I usually get pretty accurate Porsche Germany infos but it is difficult to get infos from PCNA. BTW: don't be too sure about allocation, allocations can change very suddenly and with the 997 showing up soon, I'm not sure all allocations of 996 narrow body based cars will be met. Of course Porsche still wants to sell the 996 but some dealers might even be afraid to order too many cars, even GT3, with the 997 just around the corner.
