The only way we'd see a "reunion" of the Old EV would be if that crazy VH1 show "tried" to put the band back together for a single gig. And I have a feeling one or more former members would slam their doors on VH1's face.
Edit: Oh and the only "new album" we'd be seeing for a while might be a live album if Wind-Up is desperate for money. There was an HD audio site that talked about recording audio at an EV concert
