News on the SDM II would only come with lenses using it.
Acknowledge the problem - this could be dangerous (I can see a lot of FUD being spread, e.g. "SDM will fail, it's now official"); besides most likely right now the defect rate is similar to the competition. IMO the best way is to launch a SDM II and boast it's increased reliability and speed.
News on possible new lenses - like "maybe we'll launch a XXmm f/y.y lens, maybe not"?
We'll see new lenses, I'm sure of that; but we won't see another roadmap.
I'd like to think that products like the new K-5 are very encouraging
