I also like this news. Although I like the Lotus team, they cannot offer Kimi a real chance of the world title. They are not consistent enough, make strategically bad calls now and then and cannot keep up with developing the car over the year.
I do not see why Bianchi is so special? He only got in the picture in the first couple of races, because Caterham did not build a new car and was to slow before the Barcelona updates. Chilton also not very difficult to beat, since the guy is consistent but lacks raw speed. Van der Garde & Pic beat him almost every race for a couple of months. Besides that recently let go Sauber third driver Robin Frijns beat him in World Series by Renault last year in his debut season, while Bianchi already had a couple of crash-filled seasons in GP2 before.
Massa can be luckily if he is allowed to finish his career at Sauber. I do not see why Lotus would be interested. I agree that they will probably go for Hülkenberg and stick with Grosjean, who has stayed out of troubles recently.
