Robbie's Harley will still show up in James Gunn's Suicide Squad sequel, that's pretty much her last chance to crawl back from this film's wreckage. Maybe they'll toss some quip in that movie making this one a Canon Discontinuity and just move on from there if TSS is a success, but the Birds themselves other than Harley should be pretty much done for.
