Got my copy from amazon last night.
Boy is it purdy. It really exceeded my expectations production-value-wise. I am used to 256 page B&W books costing $35 these days. For a much bigger full color book, $40 MSRP is a value.
The revised healer and arcanist is sort of cool. I expected them to do something more drastic with the magic; I guess I anticipated something else when they were talking about making it feel more like the MMORPG. Its more the case that they made the classes fit better, but didn't shift the mechanics that fundamentally (though they did shift to using AU/E style racial classes and magic.)
I was afraid they were going to make a train wreck were compatibility was concerned, but I can see it working.
