Yes it's the 12/13 model, however I THINK most of the 2013 Yes line was produced at GST, which would make this a preproduction model. I could be wrong on that though. It rode great so I never really looked into it, just wanted to include the fact it was Nidecker in case that was an issue for anyone. For what it's worth I thought it rides just as described in BA's review and I would assume most of the decks he reviews are preproduction.
I talked with the guy who I got the Greats from and he said this was in fact a preproduction model, however he was able to confirm that it was pressed at Nidecker's main facility in Europe, not their remote plant in Tunisia which apparently had some quality control issues and was a big reason for the move to GST.
You can see the 'Manufactured by Nidecker' stamp on the side in this video to confirm this is the same board.
