I gotta admit, I'm still surprised that this happened, although, looking back, you can really see this one coming. I feel bad about Mangini. To me, he was a part of the band, and all this time he took those questions from Portnoy with a smile. I remember watching auditions, and I don't know a lot about drumming, but that guy seemed like the antithesis of MP. And he even agreed to make an album about MP even if he badmouthed them (actually, he was badmouthing LaBrie on that Brazilian radio station).
But since then, Mike has played it smart. First playing live with Rudess on that Prog Cruise, then a solo album for Petrucci, then finally going to DT gigs, warming everybody up to the idea (I guess that picture with him and LaBrie meant exactly what everybody hoped for), and then a new LTE and solo tour with Petrucci. Still, I thought Mike would be afraid to rejoin again because of the pressure, and it seems I was wrong. More than their live performances (which I don't think will change a lot from the previous couple of tours), I'm really curious about the next album. Their last two with MP, to me, sounded like they were stuck in a rut of some sort. Since then, Dream Theater has gone in all directions, just as MP has with his projects, so I have to admit that I really have high expectations for the next album.
