Unless Apple goes and develops a new line of optical drives that are physically smaller (or leaves one out all together), making their powerbooks any smaller will not be possible.
Allow me to explain.
The Matshita UJ-845B Slotloading Optical Drive used in the Powerbooks is 1/8" thinner than the powerbook itself. That being the case, the only location that they could take the space from is the screen itself. Given the size of current LCD Panels and backlights, it would really not be possible for them to do that.
I could imagine them reducing the size of the 12" powerbooks as they are already pretty oversized. It is also surprising to see the 12" weigh in as the same as my 17".
It would be a little more likely that they make the units 20% lighter through reducing the weight of the materials used in the production, however reducing the height may not be physically possible unless they have convinced an optical drive manufacturer into some really interesting redesigns.
Umm there are optical drives that are smaller then .5 of an inch. Don't know about DVD burners though.
