I can only go by the things I have read so far online, as I don't own the book, and most likely won't get it, either.
The concepts of the new skill system I do like.
If they're really good when they design the 4th edition, they will manage to fit BAB, Saves and Spellcasting into this advancement type, too (provided they just aim for a simplified approach).
Basically, the new skill system is a kind of Base Attack Bonus system for skills, and I like the idea. I would prefer three types of advancement (maybe 1/2, 3/4 and full level as bonus) instead of just two, but that's details.
The only reasonable alternative would be to make everything a skill, and I don't think that would do D&D (as we know and hack & slash it) any good.
I don't think the damage track should or needs to be incorporated, even though I like the mechanics. If they want to keep the 5d6-206d6 fireballs along with 2d6 greatswords, the system won't work as well as it might do in Starwars.
Triple hitpoints at 1st level are only needed if you regular 1st level attacks deal 3dx points of damage instead of 1dx. Still, it might not be such a bad idea. (After all, in 3.x, you still got quadruple skillpoints, why not triple hit dice?)
I like the idea of having all types of defense being a DC, including the saves. I am not convinced that using Reflex for AC is such a good idea, but armor class/defense rules are always hard to do well.
