My favourite prog albums released this year so far would have to be Omega from Asia and One Among the Living from Mystery (both Yes-related). Does The Living Tree from Anderson/Wakeman count? It's just the pair of them, and more strripped down. Homebrew 4 from Steve Howe is demos. That's about it for studio albums for me.
So far Pure Reason Revolution's Hammer and Anvil is up there. It's far from being pure Prog, but the songwriting is pretty much the same as on The Dark Third (if trending towards shorter pieces), they've managed to integrate the electro bits which seemed awkward on Amor Vincit Omnia into their sound more cohesively, and have gotten heavier (but not in the Metal sense, more like Pendulum or The Prodigy).
Jaga Jazzist's One-Armed Bandit is amazing in every way.
Field Music's Measure may not be quite as good as the offshoot The Week That Was, which produced one of the best albums of 2008, but it's quite pleasing and a quiet grower.
Carptree's Nymf may be their best, most cohesive album yet.
I still have a lot to check out. Like Glass Hammer's latest, which is on its way, but I've heard really good things about it.
Jeez, how could I have forgotten Stick men's Soup? Much better than anyone had any right to expect, I would say. Yes, Levin and Mastellotto both have an impeccable pedigree, but being great musicians doesn't necessarily mean you're great song writers.
