*sigh*
Here's the problem as I see it. For the last 4 to 5 years Kamelot's image is Khan based. Their marketing has been targeted at the pop-goths. Khan was marketed as a sex symbol (in looks and voice). That's fine. It's their choice. But what are they going to do with a new vocalist? I get, sing the old material, fine. But at that point you are a tribute band (even if the writer is still there, none of them are especially skilled instrumentally, so any tribute band can do what they can do at this point). Thomas is the writer, the music is his, so I want to know what new direction he will take this band. If he gets another singer to continue the goth-pop then its unlikely I will enjoy their next release. But if he continues with Fabio (or somebody similar) and goes back to being a heavier prog/power metal band, then I think its quite likely I'll enjoy the next release.
So I need to know the direction of the future of Kamelot, before I care who sings for them. I'm not interested in who is going to lead the tribute band. I don't need to see a singer who can sound like Khan (some of the same people who railed against Journey's choice to drop JSS, got hard at the idea of certain sound-alikes).
