Just confirmed by Felipe Massa on Twitter that he will not be racing for the Scuderia in 2014. He posted the following on his Instagram account:

From 2014 i will no longer be driving for Ferrari. I would like to thank the team for all the victories and incredible moments experienced together. Thank you also to my wife and all of my family, to my fans and all my Sponsors. From each one of you I have always received a great support! Right now I want to push as hard as possible with Ferrari for the remaining 7 races. For next year, I want to find a team that can give me a competitive car to win many more races and challenge for the Championship which remains my greatest objective! Thank you all.

Felipe

Farewell, its a shame it didn't pan out better in 2008. I'll miss the [Rob] Smidley/Massa commentary during the race.
