The rumors I read a few months ago was Rossi, Kubica & Hekkie Kovalainen. Rossi in a Stobart/Monster venture and the other two self-funding drives for a few years if they cannot make any progress in F1. I would bet that Kubica was about ready to jump ship in a few years regardless of how good Renault was (before his accident he was in a rally car every few weeks mucking around). Kovi owns many rally cars as well but I am not sure how good either would be in the WRC.
