I think it's hard to predict.
Brawn could be at the front, but despite last weekend's result, for now I find it hard to believe that they are genuine contenders this year and I think they will not have it so easy at Sepang. Red Bull, Toyota, BMW and Williams are perhaps in the running too, based on last weekend's race. And who would be surprised if one of the "big two" teams made some crazy leap forward - perhaps not to the front, but at least towards the solid points paying positions? Not I.
I think that it is at least a change from the norm, and surely it's a good thing.
