As I'm also a member of your IPF wiki spaces you'll appreciate my additional dillema. If I want to use Canon's Export Module I need to be in Photoshop. As far as I know you can't access it from LR, but maybe I'm wrong. That being the case, if I do use LR 2.0 in lieu of PK Sharpener for output sharpening the work flow would be something like this:
1. Open and apply adjustments in LR
2. Softproof and adjust in Photoshop
3. Output sharpen in LR
4. Print from export module in Photoshop
Clearly a pain, and a case for PK Sharpener for Canon printer users. But I've had a nagging feeling that PK Sharpener may not hang on after LR 2.0 if it's functionality and future upgrades are going to be covered in LR.
