The Esprit was pushed back about 12 months (on top of the other delays) and the Evora S roll out is really dependent on the success of the NA Evora. The S is already engineered and ready to go. It's simply a matter of market conditions.
The S3 Elise/ Exige are well into the design stage last I heard. They could easily be here by 2012 if Lotus chooses to.
