Since you aren't giving me a neutral option, I'm going with thumbs down.
The last shreds of D&D left behind in 3e look are being stripped away, leaving only goofy superficial choices (Attributes still run 3-18+? Why?!). I lost all interest in 3e/3.5 some time ago, and nothing I've seen so far with 4e is poised to bring me back into the fold. Maybe if Living Greyhawk was going to soldier on, but it's being put out to pasture. So with that, I'm done. I'm sure many people will be happy with it, but this just isn't D&D to me anymore. Maybe 8 years from now, when WotC "reinvents" the game again.
That said, I am interested to see how they are going to handle encounters, monster roles, and building terrain and obstacles into the encounter. I'm eager to see if it suffers from the same complications as Iron Heroes.
