An update for 2.0L SD:
We are now in the stage of testing actual tuning/driveability of SD 2.0L on our internal vehicles. Things are going well, but we still don't have an ETA on release. There are numerous changes required of the 2.0L ECU to get SD to be a complete solution (much more than 2.5L needed), so there is quite a bit to test/verify.
