Here's the reply from Boss for anyone interested,
John,
Thank you for contacting THE BOSS Snowplow. Yes, we will be reviewing the Viking later this year. If all testing and design go as planned, we hope to have an offering for early in the 2014 season. I would suggest staying in touch with your local BOSS Dealer or feel free to check back with the factory for updates.
Thank you.
