Classic Rock Artist's later era albums. Will any of these ever become "classic"?

No, to answer the OP's question.

That doesn't mean these artists have not made solid records which are enjoyed by many. or that the records are without merit. But a classic record is a cultural thing, not a fan saying this record is great.
That being said, in my opinion, and of the ones you all have listed which I've heard, less than 5 of those albums would I even consider great.

 

"Egypt Station" should be considered a classic. Whether it will ever be considered one is hard to say.
