I overlooked the following part:
"► The weight gain from these new smaller engines may be used by the manufacturers to install energy retrieval systems."
So they could be using part of the ~125kg to install KERS like systems.

As was stated earlier in the thread, the only consequence is much lower engine reliability when you try to squeeze too much horsepower out of a smaller engine. It will also need to be rebuilt more often and replaced more often.

Well they mentioned they target a 150hp decrease in horsepower, so I assume they will keep restrictor and pressure regulations such that the intended reduction is more or less retained. Don't think they explicitly mention those 2011 restrictor and pressure regulation in the presentation though.
