I concur. There is no evidence that Raikkonen will return. Wanting it to happen does not qualify as “evidence”; likewise, I fail to see how McLaren ending their deal with Mercedes is representative of anything. Like most Kimi fanboys, I see you’re having a hard time moving on.
Besides, while there is speculation in the media about the futures of Button and Hamilton, McLaren have made it quite clear that they want both drivers before any others.
