Yeah, one would say they have gathered some data this year. In that respect it's a good thing the PU's aren't changing, would be a bummer to start all over again.
But still I'd love to see the power-2-weight ratio to increase significantly. Lighter cars, bigger fuel-flow, more revs and back to 5 PU's/yr. The cost of engines is not in producing the 3-5 PU's/yr, but in the R&D.
Current format isn't about racing, but to consolidate PU and tires; efficiency over speed.
But hoping for that to change is in vein in this over-grethanized world ..
