One important thing that's missing from the discussion is how much profits record companies make from vinyl records vs cds. Records may bring in higher revenues but they are also much more expensive to manufacture, store and distribute. I doubt they make more money from records actually.
As a long time record enthusiast (I never stopped buying records, or sold any of my earlier collection), I think the whole "vinyl revival" has become ridiculous. To me, the CD market seems to be in the exact position where records were 30 years ago. Dismissed as being outdated and dying, and not cool. My buying of CDs has slowed down a lot but it's more of a function of the disappearing cd shops locally and my becoming more selective of what I buy generally. However I do intend to focus a bit more on cds going forward, given the absurd prices (& sometimes dodgy quality) of used and new vinyl records.
My bigger worry is the long term maintenance of my CD player. But that's for another discussion.
