Their last great album was still with Mike - Black Clouds and Silver Linings.
Most people consider that a fairly limp end to the MP Era, and that maybe he was right, that the band needed a break.
The Mangini Era is filled with excellent albums and great tunes. Not saying you did this, but a lot of people dismissed it out of hand, and I never understood that. I actually liked what they were doing, and I've ultimately been lukewarm about MP coming back. I think the way that the band is run can certainly use his input, but musically, not so much.
I heard the first song from the upcoming album and I don't think it is going to make me run out and buy the album. The song was okay but it didn't really hit home for me beyond that.
The ultimate key to Night Terror will be being able to latch onto the instrumental section, and that ain't going to happen in only a couple of listens.
