I can't wait, hopefully Sauber and Lotus will get a greater chance to show of their pace and pick up some valuable points.
McLaren to be strongest again I think, but will it be Button or Hamilton? How will Hamilton respond? He was very despondent after Australia.
One would hope that Lewis doesn't let defeat get to him, as we've seen it do before. To be honest, in combat at Melbourne, he wasn't at his best 
Normally he comes back pretty hard after a loss to Button, this happened numerous times in 2011.
Don't forget what he said before the race weekend - "We are aiming for good points, not necessarily victory". The way he drove in Melbourne, it looked very much like 'safety first', and probably thought his teammate would be somewhere near him. In overall I think he was shocked with Button sprinting from the get go.
You can bet he'll go 100% from now on, knowing he's already behind by 1. If he loses again pacewise in Malaysia, something is seriously wrong. In his head.
