To me thats the right apporach. I was not expecting much change and besides why fix it if it aint broke?
The problem is that the regulation changes are a) more numerous, and b) more specific than most are saying.
We all know about the refueling ban and the skinny front tires, and the changes that thus must be made to accommodate them. These changes are not only mechanical (longer wheelbase, longer car generally to sort the weight distribution, etc.), but there is certainly an aerodynamic interaction to consider, as well. For instance, the narrower tires will create more space between the wheels, which will certainly effect the aerodynamic balance and efficiency of the car.
Then there are changes that no one is talking about. The ban on wheel rim-heaters is being discussed by no one, yet it might be the most important change in the technical regulations, as it's going to make bringing tires into the optimal operating temperature range more difficult. You can have the design down well and be generating plenty of grip, but as the BGP 001 demonstrated last year, if you can't get the tires to work, you don't have a fast car.
Then there's the ban on wheel covers, which will reduce aerodynamic efficiency a lot.
There were some pretty major rethinks required for this year. It seems to me right now that McLaren is the only one who has dotted all of the "Is" and crossed all of the "Ts." I'd be surprised if Newey didn't, as well, as he is one who is usually on top of regulations changes. (2005 with the tire change ban comes to mind.)
