Eureka was announced, but entirely devoid of context, so I'm not sure how I can feel about it. My original theory years back was that it would open up as optional content after Syrcus Tower was used for plot purposes, but the only indirect continuity we've gotten out of it since came from the very end of 3.4, and Nero's still too much of an unknown to say. Since they've announced the 2.X and 3.X patch-series stories will be skippable, maybe they'll just bite the bullet and make CT an additional requirement for whatever quest ties the Triad back into the MSQ (and thus include it in the "skip"), since this will probably be the last patch cycle where it can be cleared through DF. That would also let them drop it as a hard requirement for Eureka without having to write Eureka like the former never happened. The alternative is the Estinien card, where he addresses you like you've done 30-50 DRG even if you haven't. Either way, it's not something that can be left alone anymore.

But Yoshida has been playing the entire thing way too close to his chest. I'm hoping that's because there's actually something that he can't be trusted to keep secret if he talks.
