Actually, when you consider the banning of EBD, they needed a different ethos at the back. So they had to use those god awful exhausts at the start of the year.
Allied to this, the front of the car uses Pull-rod front suspension which is different from the push rods they ran for many years.

The requirments are new geometries, set ups etc not to mention you have to be spot on in your tyre calculations, because if you get it wrong you don't have a reference to go back to.
Of course there are carry over parts, you still use the same engine, KERS and gearbox and the requirements for these will not have changed much from 2011 through to 2012. The packaging will be near the same, meaning your basic shape will be retained. There is very little scope for development on this front, due to the minimum mass regulations as well as the dimensions as stipulated by the FIA.
So when Adamski talks of a new car, he is saying the F2012 is a massive departure from the F150th.
Should Mercedes go forward and try pull rod front's, as well as a better rear end philosophy? Of course, and this is where I think there will naturally be some carry over parts from the W03, which cannot really be changed due to stringent regulations. However big changes are being mooted which can in this current formula be called a "new car".
