Lewis Williamson (Red Bull young driver) has been replaced by his FR3.5 team, due to poor results: http://www.italiaracing.net/notizia.asp?id=36264&cat=5
Kobayashi's gone from being a good and exciting driver to one of the drivers. In 09 and 2010 he was good and exciting and very enjoyable to watch. His 2011 season was also good but it was out of site and under the radar. Now he's being consistently beat by his teammate and hardly ever gets screen time and everything seems to go wrong for him. He's become Perez's teammate.
