Yes, there will be a domestic release.
Currently I think it's only available here: http://elp.merchnow.com/products/201612/trilogy-deluxe-edition-3cd
But there should be other domestic retailers that put it up for preorder sooner than later.
This follows the usual procedure for these ELP deluxe reissues. Sony releases them first, and then Razor & Tie put out their identical version like a month or so later.
That's a pretty good price on that site. Too late for me though, I already ordered from amazon.uk since I was ordering Rollerball (original, not remake) on Blu-ray and it's already "dispatched".
Sure looks funny to see a dvd-audio logo right next to a Sony logo. Sony are such losers. Won't even use a format they invented.
So how complicated would it be to rip dvd-audio so I can play it on this jRiver thingie? Probably too costly I would guess.
