At this point (and really since Ghost Opera) Kamelot is a band that does one thing. They happen to do that one thing really well, and it happens to be a thing I really like, so I don't mind too much if they keep making more iterations of that one thing. I do hope that their next album is not Haven Part 3, but I don't expect anything innovative from them at this point.
Seventh Wonder, on the other hand, still feels like it has a lot of creative potential. They feel like a band that could still have their best album in them (whereas Kamelot's best album is your pick of Karma/Epica/The Black Halo, and nothing's coming along to change that). And, this may be controversial, but I think Tiara is my favorite SW album yet (the last three are all really close, though). So I'm glad to see that they're keeping the momentum going, and definitely look forward to new Seventh Wonder with great anticipation than I look forward to Sacrimony Part 4, despite the fact that I'll probably enjoy that, too.
