I'm hoping for:
Anubis Gate
Circus Maximus - with a whole new set
Andromeda - also with new album
Any of steven wilson's bands would be awesome to see live. It seems like he only plays the largest cities anymore like New York/LA/London, etc. Probably will never see him if that stays true.
progpower is a major event for me, and it takes a lot of time, money and I can't imagine how hard it is for the bands, and their preparations to rehearse special performances, etc. Pretty amazing how it all comes together. It is absolutely crazy how a new drummer can fill in for a show with just a week's rehearsal time "native construct", or how other singers can fit right into another band's act and sound completely natural (dragonland with britney) and (voyager / dc cooper). They must be working hard behind the scenes to make the show special. And all the unexpected stuff that happens but gets worked out in seconds.
Haken and Fates Warning are the main event for me right now for next year. The rest are not enough to justify the price to get there for me right now. I think the ticket price is cheap for what you get, but the time and effort to get there is the hard part. It's a pretty intense 5-6 day journey, and then if you get sick afterwards like I did this time, it takes even longer to get back to regular life. It was pretty rough on me this time, but the line-up was certainly worth it, despite the changes in bands. Anubis Gate - I think a high majority of the audience still wants to see them perform if there is a way. I was very disappointed they couldn't make it. They are a headliner to me.
