Not that anyone expected anything different, Kamui has issued a statement that he won't drive the next two GP:s...:
“Unfortunately, due to team’s situation, I will not able to race in United States GP and Brazilian GP. I am very sorry for the fans looking forward those races. While I am carefully observing the situation, I will evaluate possibilities and make best choice for my future.”
I've also read that Marcus hasn't heard a single word from anyone at Caterham since the situation escalated.
So this should be it for him in F1
Even though he deserved a chance in a better car he still had a very solid career, 125 points, a home podium and usually getting the better of his teammates is nothing to be sniffed at.
