I'm sure Ferrari will be the team to beat in 2008, but I'm not so sure about McLaren. The whole spy saga may have a negative effect on them, they lost Alonso, whose car-developing skills are really good and their form used to resemble a sinusoid: 2003 - super, 2004 - not so good, 2005 - super, 2006- not so good, 2007- super, 2008 - ...?
I hope Renault will be back as frontrunners, as I'm always rooting for them.
Lindsay, thanks for updating the opening post!
