I actually talked to them like a week ago, they said they don't have any official plans to offer services for HTML5 developers, but that they probably will in the future.
Also... They don't just help flash developers, they will help any game developer using any format to find a sponsor/buyer for their game, just e-mail them and ask them about the specifics. Even if its not a browser-based game, they will just send it to any parties that they think might be interested.
