Vinyl is both a physical and analogue format, superior to digital in both respects, and that's why it'll survive CD, SACD, or any other digital format.  Vinyl never went away, it was only discarded by those who must have the latest plaything (a lot of those people are now regretting it and returning to real Analogue audio on Vinyl) - so Vinyl lives on - and it is now picking up pace yet again.

The sales and model releases of brand new Turntables are on the up, and the sheer amount of weekly new releases on Vinyl is further proof of the trend.  On the DJ scene, some venues (usually the the really classy ones) won't let you anywhere near the 'buseness end' of their venue unless you use real Vinyl.

Last but not least, Vinyl is sooooooooo much cooler than a digital rig as is demonstrated in the attached photo..  But yup, Vinyl is far superior to any CD out there, and those that can't tell or think it's the other way around, really should invest in better quality audio gear.
