I'm not in tune with the mainstream, but with the bands I listen to, I see it going two ways. Yes, there's an increase in digital-only releases, but there has also been a significant increase in deluxe box set versions of physical releases. I like to support these kinds of releases because there's usually some cool bonus stuff you get, and even though they don't usually arrive on or by the release date, they usually give you a way to download the music while you wait. I like this best-of-both-worlds approach, and I hope it continues.
