@Frosty: is there any word about RB using Kers? It seems like only a few teams are confident enough to start with it.
BTW judging from the report they are better off first sorting out their transmission instead of fooling around with kers 
This is what was said in recent interviews from the F1 website
"Q: Flavio Briatore said that Renault will start the season in Melbourne with KERS. What will Red Bull Racing do? Will you be running the Renault KERS, if you choose to run it?
CH: We have an excellent relationship with Renault, and we are working very closely with them on the side of KERS. Flavio has been extremely good in opening his technology to Red Bull Racing. We will only run KERS when it proves to be a performance advantage, so we will test it extensively during pre-season running and make a decision shortly before Melbourne, if we will run it or not. Time will tell. But as I said we are working very closely with Renault and I am pretty sure that will speed up the development phase."
Q: Will you use KERS in Australia?
AN: We will run it when we feel we are ready to run it and that it will definitely be a benefit. It will also have to justify its cost, because for the flyaway races for examples, the shipping and freight costs involved are very high. At the moment, it is not yet clear what advantage KERS will bring in terms of helping a driver to overtake. Perhaps the biggest risk of not running KERS is the chance of being overtaken at the start or at a re-start after a safety car period.
