Companies release their new product at their own pace. No exact release date. I've seen a lot of sites have some of like ride, lib tech, burton, and some of the big names stuff. A lot of companies have the full 2013 line up updated on their site. Some don't. I havent seen never summer, academy, or some others on any sites to buy it or on their own site yet.
You can search you-tube for the sia trade show and they have video of a lot of new stuff from it.
