The Trix are pretty much bound to return at some point. Apparently S4 wasn't well-received because the Trix weren't in it (among other reasons, of course), so I don't think they'd try it again unless they  really can't think of anything for them to do.

If they didn't reduce the Trix to being jokes, I'd be all for seeing them again. Plus, I doubt they'll do anything that delves into the Trix's history to keep them as villains who do evil things because they're unquestionably evil.
