Not with you at all, I'm afraid. A change is as good as a break, and they've got a new drummer, a new band leader, a new status quo with a new ethos, increased contributions from John Myung, outside producers on the vocals, Mike Mangini will be writing on the next album... they're fine for change, right now!
I love weirdness, and revel in changes, but they've only just had the biggest one of their career! Do I hope the new album surprises me, and treads new ground, and proves Dream Theater are capable of working in new formats and doing new things I would have never expected to hear on a DT album? Yep, totally. But they've just endured their biggest change in 20-odd years. They're hardly slouching.
