Bruno, I don't think Apple is ever going to invest in a delivery mechanism that is slowly dying off (DVDs). Haven't bought a DVD in years.
On the other hand Logic is definitely not dead. With the new technology platform that is Final Cut X I suspect that Apple may be planing something similar and starting from scratch takes time.
The end goal I'm sure is to harmonize the applications to deliver a similar or better integration that what Adobe offers with their products.
By the time you factor in the massive price drops that Apple has introduced (just take a look at what Logic, Final Cut X, and Motion cost today vs previously) Apple is if anything aggressive about growing market share.
