Will cassette tapes ever make a comeback?

I ask this question, because I have about a 1,000 cassette tapes that I am ready to give to Goodwill. Seems like I read an article that stated that cassette tapes are coming back to replace CD’s. If this is the case, I will save my tapes and sell them, rather than give them to Goodwill. 90% of my tapes are by the original artists and in great shape. Question: has anyone heard a rumor that cassette tapes are making a comeback and why?
