The CLS is here now. Very interesting look for a limousine.
The AMG version comes out next year with the E55 engine and HP figure. The CLS 55 AMG is around 6000 Euro more than the E55 AMG.

Interesting: the CLS 55 AMG has 255/18 wheels front and 285/18 wheels on the rear, pretty nice.
19'' wheels with same tire width are available too as a low cost option (slightly under 800 Euro).
Also interesting: the CLS 55 AMG is 85 kg heavier than the E 55 AMG.
