It's safe to say that with drummer Mike Mangini firmly installed behind the kit and appearing on his second album, prog icons Dream Theater have moved on from former skinsman and band co-founder Mike Portnoy, who left the band in 2010 amid fill-in work for Avenged Sevenfold and a request for a break. But how does Portnoy really feel about a possible return to the band?

His requested and much-needed break is over and while Portnoy has also moved on with the Winery Dogs and other assorted and sundry post-Dream Theater projects, he remains wide open to the idea of a reunion with his former mates, even if they aren't.

In a chat with Radio Futuro (quote via Music Radar), Portnoy said, "I would do it in a heartbeat," when asked if he'd rejoin the band of which he was a member for two decades.

He continued, "I've only needed a break, and I've had that break. So I'm ready, willing and able. But I honestly don't think they ever will; they've closed their door on it and I think they're too headstrong in having to prove themselves without me. So I wouldn't count on it. But my door is always open."

When Portnoy left, Dream Theater brought Mangini in. He played on 2011's 'A Dramatic Turn of Events' and he also participated actively in writing and recording 'Dream Theater,' out this September. The band seems happy with Portnoy's replacement, but as rock fans know, reunion tours are always cash cows and fan-friendly events.
