Replying to Are next years park skis much better than this years?

I've been wondering if there's any reason to wait until next year to buy new skis. I don't need new skis right now, but I'm thinking I might come over some nice offers post-season. So my question is if you know about any significant improvements on next years skis that I should wait for... Right now I use some Head J.O. Pros, which in my mind are too stiff and too thin on the middle. I also found out that I should be using longer skis than 169s (my first twintip season). I've been looking at Line skis, as they seem to fit my needs better, and I like Line more as a company because of the traveling circus etc. I love this years Anthem graphics, and I hate next years Anthem graphics! I'm interested in other brands too. Should I wait until next season?
