Not sure how well I can rank them at this point, but my favorites are the new Riverside, Katatonia, Insomnium, Ellereve, and Caroline Polachek.
The Kamelot, Ne Obliviscaris, Delain, and Haken are all okay too, but I need to listen more if I'm ever going to love them, and I doubt that'll happen with Haken at this point.
Biggest disappointment—and this is probably just a consequence of unreasonable expectations—is Enslaved's Heimdal. Not sure why, it just hasn't clicked with me yet.
