Yeah, about that Outcry pt 2:
There definitely are many ADTOE/IAW similarities, we proved that many times until now. Those structural similarities couldn't be pure coincidence, and DT had to be aware of them, not only aware, they INTENTIONALLY made the albums similar. And guess what, Petrucci was asked about those similarities in an interview, and again guess what, he denied them. I wouldn't be surprised if they actually planned this for some time (since 2011 at least): they were going to make a concept album based on a song, since Outcry has similarities with Metropolis, the new album may actually be called Outcry pt 2: The Astonishing.
There are also more things adding up to the hypothesis, like similarities between self-titled and Awake, as well as FII was intended to be a double album, including the song Metropolis pt 2, but they weren't allowed to do that. And now that they're allowed...
This is all pure speculation (not that random though), and I'm saying don't be that surprised if DT comes one day and announces full album name actually is Outcry pt. 2: The Astonishing
I mean, I will definitely be hyped AF, but not surprised.
