Sales of vinyl have gone up for the first time since 1997. However, if you look at the entire pie, the sales were only some million+ or so, making it just a blip on the radar.
Vinyl is still a niche medium. If you look at the top 10 sellers for 2014, 5 of them are old albums (2 by Oasis, 1 by Led Zep, 1 by The Stone Roses and 1 by Floyd) and one is a new album by an old band (Floyd).
So it is more of a novelty than something that will rescue the music industry.
