This has been covered several times before. Most notably in the Lotus Renault GP thread.
While the livery will be on display at next week's Autosport International, I think we're going to do what we did last year and have indiviual threads on the car launches. But like race threads, there is no need to make them a whole week in advance. The day of the launch should be enough - especially since the R31 is not being launched until the Valencia test on January 31st. So I'm not really seeing a reason to keep this thead open.
