I can't see the significance of this announcement.
Has Gilles Simon done something wrong?
Has Luca Marmorini been on gardening leave from Toyota since January?
Very strange to do something like this at the end of the season imo (even if Ferrari are only fighting for 3rd in the CWC wiht McLaren)
Also a bit of a strange amount of gardening leave too (8 months by my reckoning)
Dont think there is much major significance though
