With the release of F1 2010, Codemasters already said words on next version i.e. F1 2011. Codemasters confirmed at Gamescom that F1 2011 will have an interesting feature.
Steve Hood, Chief Game Designer has mentioned in a conversation that, in F1 2011 a split-screen mode is included. Thus, the two players will be able to play on one console.
