...And reposted from Planet-9:
[The 911] will evolve into a more luxurious 2+0 GT and move "upmarket"
The Cayman/Boxster will also move upmarket as a new 4 cylinder entry level
roadster will be developed with VAG (the '356")
The new cars will be bigger, more powerful, more economical, more expensive and not look much different than the current cars.
