Derek had amazing groove! Now that Derek is gone from dream theater, So is the groove. and that's a fact.
Um no, still just opinion.
My controversial opinion of the day: 2 more albums after this new one. I'm calling it.
I think their work ethic and their reason to get right out there even when MP wanted to "take a break" will prove you wrong. They love to make albums and tour.
Another two albums = 4 years. Petrucci & Myung won't even be 50 by then. The rest of them will be mid 50's at most apart from Jordan who will be pushing 60.
I don't think age will be the issue necessarily. Then again, remember that video snippet a few years back where JP had to put on some heat braces for his arms, and MP needing massages every day to be able to play? I don't think you can assume the guys are all in perfect health just because we don't hear anything.
But, I think the real reason to stop would be lack of interest from the public. And that I think is realistic 2 albums from now.
I think you're mixing up own opinion with public opinion here. DT appears to be remaining very steady in terms of popularity, so I don't think lack of interest will be any reason to stop.
Age or lineup will be the most likely reason, and while their demanding music does have its issues as you've mentioned, I think they'll just start easing up on the balls to the wall stuff, and maybe go lighter on touring and recording, rather than sticking to the 2 year schedule.
And when did this thread turn from controversial opinions to controversial theories anyway?!
