For the sporting contest fans it should be great.
DRS and KERS about perfected to enable passing.
Degrading Pirrellis.
The Hamilton move, good or bad, will lead to a certain amount of uncontrolled aggression.
With the settled regulations Adrian will have about run out of wriggle room, and will be more interested in 2014 anyway.
RBR, McLaren, Ferrari and Lotus should be competitive with Mercedes and Sauber a threat.
The internal battle at Torro Rosso wil be interesting and may lead either of the drivers to surprise on accaisions.
Plenty of potential for a good season for the drivers championship.
For technuts like me it will be frustrating, but then we have 2014 to look forward to.
