I don't think so. I expect the minimum weight at 640 kg like 2011. These dedicated engines should save 30 kg including the turbo charger and turbo compounder. This additional weight can go into the AWKERS system. They may decide to standardize the turbo system in the first year to limit the cost race. At least that has been reported in fall by the EWG. So cost wise it may not even be such a problem.

Depending of the KERS system they can reach the same top power as before. It should become the focal point of competitive development. Nice prospect for a change to get something mechanical on the chassis side instead of the boring aero stuff.

The more we compensate the power with it, the more artificial and less driver dependent the racing becomes. That HERS and KERS will more likely be computer regulated and track position dependent.
In actuality we'll just have weak, heavy, easy to drive 580hp cars with a big electric boost for the straights.
Again I disagree. The only sensible way forward for high electrical KERS efficiency is using a dual torque mode instead of a boost button. It means the electric torque is fed at exactly the same rate as the engine torque. Drivability will actually improve as the power is put down by all four wheels.

Anything around 9,000-10,000 rpm will be just fine. A turbo engine doesn't need mad rpm to perform. It is much torquier and much more drivable. I would be surprised if they would be using more than 5 engines. Getting the engine numbers down will help compensating for the cost of KERS.
