the artist's website, or their label's website, generally contain the anouncement in advance of release.
For those who buy new releases on vinyl
What is the best source for knowing what new releases (ie, music which an artist is currently releasing, not reissues) are coming to market? Specifically, I'm interested in how best to tell if something I want will or might be released on vinyl so as to avoid buying the CD and then finding out that it's coming out on vinyl.
