I was a thumbs up, not a wink. The wink is just incidental!
To me those things sound pretty standard for DT, even for a non concept album. I'm sure they've talked about having a clear focus and a theme/concept to an album for many of their albums (maybe not in those exact words, but terms that could easily be interpreted that way).
Just to make it clear, I'm not trying to negate the idea, I just don't personally feel like there's been enough evidence to have any expectation of one. I really won't mind either way, as long as it's good music, I just don't fully understand why some people get so excited at the idea.
And again, that's even taking into account that I think SFAM is damn near untouchable!
Also the concept is always explained in the title: Octavarium (number 8), A Dramatic Turn of Events, Black Clouds and Silver Linings (as you've already said). The next one hasn't got a title, so it's pretty unlikely we'll have a clear concept
Only one of those is a concept album in my opinion. And just because that is a pattern that exists in the past, it doesn't act as a requirement of the new record (which does have a title). Even if it did, who's to say it's not going to be a concept album about a Theater of Dreams?
None of them is a concept album! DAAAAAAHHHHH it's going to be a long night.
