Regardless of what anyone may think, DC has already laid the seeds for the Titans to eventually return and have another moment of greatness.
Three seeds, actually.
Teen Titans, the cartoon.
Teen Titans, Go!
Titans, the tv show
The younger fans of the cartoons will eventually hit the nostalgia point and there will be a push, either initiated by them or DC's marketing, to bring the characters back in either another animated series or a comic.
The tv show, Titans, apparently has some fans. And their interest could drive marketing to appeal to them in some fashion.
Not to mention, the Wolfman/Perez run is such a high water mark that collectibles and trade paperbacks will likely never stop being produced, which will only generate more interest from newer generations of readers.
So, yes, the Titans will see a return.
The question isn't really 'will they?' but rather 'when will they and how?'
