Nothing could be better for Bomber, Donek, Prior, Coiler than Burton re-entering the market. It would help get more people into the sport, and then once they get good enough they will start looking for the boutique products. I'd be surprised if Burton did get back in though.
Burton fought for alpine from day one and continued fighting pretty long after it was uncool. They kicked alpine to the curb and pretended to hate on it when they figured it was actually hurting their image. They could have been nicer about it, but I guess I don't blame them.
I'm a big fan of Burton for the fact that a snowboarder started a snowboard company and made it the biggest, most successful snowboard company in the world. The 2nd and 3rd biggest snowboard companies are ski companies. It just wouldn't be right if a ski company was #1. When you're not wearing or holding your snowboard, nothing says "I am a snowboarder" to the world better than wearing a piece of Burton clothing.
