I am expecting Red Bull to be sandbagging, it's their usual style. The good thing is that McLaren seem well sorted out of the box and should be competitive.
Marussia and Caterham looked ok in practice two, fingers crossed they have both made good strides. Ferrari will struggle although Alonso will find a way of overdriving their new pig of a chassis. Mercedes and Force India will be competitive and once Raikkonen gets into his stride the Renault (sorry.... Lotus, yeah right.... in name only) should be getting regular points.
