Between 2009 and 2010 there was a bit of a spike in mountainboard prices (cost of production, transport and warehousing costs).
2010-2011 saw more Trampas coming into the US. A bit of a rise in Scrubs too I believe.
I think 2010 was when the Kirkman, Leafe and Robbins boards debuted.
Mountainboarding/kiteboarding is a niche market and people hold onto to boards for multiple years.
Thinning or maintaining the same total count of items in the product line is not unreasonable... especially in the still less than rosy economy.
No matter how great a board is, it costs the manufacturer money to keep them in the warehouses if they are not flying off the shelves.
