It's not really a "new AG", they just added some visual changes. I like the visual changes, hope they add the layouts that were in the beta. But most importantly, I hope they start implementing the big features mentioned in the AG3 subforum.
I have no answer. But I'll say, they didn't add a lot. Seasonal armatars are back and just a slightly different layout. At least they are showing progress though.
They might just slowly add different updates intill they can finally take a slightly larger jump then the others and the page layout changes.When that happens Killersup will call it AG3. It sure however does seem as though that the AG now feels and works alot better then what it would have in say mid summer of 2012.
