How much longer will analog cable hang on

[zenith2134]

We currently have Time Warner digital cable but they still offer the basic analog service in my neighborhood. I use it but suspect I'm one of the last ones who still does... We also have Verizon but not for t.v. and they quit providing analog tv service in 2008.
I hope the cable will continue to offer the plain analog channels but I feel like they're gonna axe it soon... Thoughts?
It's nice to use the tv's internal tuning ... without analog cable i will never really be able to use them again besides on CH 3/4 ...
