From theFwoosh Q&A:

4. If the Wind Raider is deemed successful in terms of sales so that a second vehicle will be released in 2012, when will we be told you will move forward on a release date?

Regardless of how the Windraider does, there will not be a vehicle in 2012. We are putting our resources for fall 2012 into Granamyr. We may return to a vehicle in 2013, that has not been confirmed at this time.
