I agree. After MP gets his time away from DT he will definitely rejoin. John P said himself that door is always open for Mike.
And as for Blind Guardians situation a few years back, elliedark, I admit that Thomen Stauch was an amazing drummer, but it was not as big of a deal as if Hansi or Andre left. Sadly, for DT Mike was more then just the drummer, he was the heart and soul for them. By the way, funny you should say Blind Guardian, they are my favorite band along with DT. I'm was very happy with they're latest masterpiece 'At The Edge Of Time'! lookin forward to seeing them live in November!
