Well....they're this years AK topsheet, it's also not new, this picture is a few months old. Reverse camber custom for the k2 guys. not a production ski, at least for this season.
They are one of the proto-types to a new k2 ski that is coming out for the 07/08 season. Its going to be called the hell bent. When that pic was taken they hadnt set a graffic yet, right now the final ski design is in the final stages and should be available for viewing at SIA 2007
