I definitely doubt, that it will be their best in years.
With JP taking over control completely now, the lyrics will probably be even worse than on BC&SL, which I think is one of the reasons, why neither BC&SL nor SC were really good albums despite the obvious lack of inspiration. The break MP wanted was imo the perfect way to re-ignite Dream Theater, to make them hungry again.
Instead of that the only guy with some kind of a kick-ass attitude is gone and 3 technical masters are left, who can jerk off in hyperspeed while soloing to every possible and impossible beat...but to me there is a lack of songwriting-ability and a desastrous dictator of cheesy lyrics in the remaining band....I hope I'm wrong, but I'm pretty sure, that DT11 will be the worst DT record...
