Yeah. They could. But few (zero?) studies are retracted for the sake of being proven incorrect later. And, to be far, it would be ridiculous. Imagine having your career nullified because when you're 60 some major break through shows that your studies aren't relevant anymore. Your work was good when you did it, but now there's something new. It's kind of the definition of scientific progress.

However, as a counter example, in my very narrow specialty there is a well known lab that has produced highly cited bogus studies. I've personally published opposing results and said, "these studies are wrong for these reasons" using almost exactly those words. Should they be retracted? Absolutely. Will they ever be? No. Because, of course, the publisher and the authors just point the finger back at me and say "no, you're wrong!" and that's more than enough to keep the vague debate going.
