Don't hold your breath mate.
After Christmas some of the brands that overproduced might start putting small markdowns on them. For anything serious you'll probably have to wait till spring/end of spring.
If you really need a board for cheap, I'd start looking at 2010's.
Also, I think this year is going to be a bit calmer than last year. Sierra is (at the moment to my knowledge) kinda in a bind and Burton might be cutting down on production due to last year's insanity.
