Can you give a brief overview of what's in the book?
Classes, Races, Paragon Paths (for both Races & Classes), Epic Destinies, Backgrounds, Feats, Rituals, Magic Items (mainly to support the new classes), and some minor rules clarification stuff.
Barb AC issue fixed?
I'm only vaguely aware of the issue, but I can tell you that they don't get their Con to AC as some have suggested, but they do get an AC bump.
How are shifters handled? Multiple options like the genasi? How many?
2 Shifters, the ones from the MM, but they get new stuff to play with. Their paragon path is especially vicious.
Is weapon expertise still around? Implement expertise?
Yep.
Are the decent feat options for builds that use implement powers? PHB focused on martial and had far better feats for weapons and melee . . .
Do they have any better feats for existing arcane casters (who were pretty poorly done by in PHB1 and haven't had their own splatbook like martial heroes with extra stuff yet)?
I think these are similar questions. Yep, there are new feats for any arcane casters, similar to stuff like "Burning Blizzard" but with more flavor to the different damage types. Not a lot, though.
What's the deal with the Bard rituals? Are they realy just rituals that only bards can use? Or is there something else to that?
They have "Prerequisite: Bard", and I don't see any way around it, so yeah, Bard only.
Could you give the names of the Gnome racial feats, and a general idea of what they do?
There are feats to increase their stealthy nature, and to give them more "magic trick" options.
I was curious about the Stealth updates (on DDI they show it in the table of contents preview at the end of the book)... are these major changes to how stealth works, or just some minor updates, etc
I believe these are the same changes that were in the errata, but I'd have to pick through them to be sure. They look similar.
Be back in a bit to answer more.
