Penske Not Running Busch Team in 2008?

Question: You mentioned scaling down or possibly even doing away with your Busch Series operation, which was a one-car deal this year. Why?
Penske: I think we have elected from our perspective, at least under the current circumstances, to focus on the Cup — because the cars are so different (with the Car of Tomorrow coming on line full time on the Cup side next season). Now if you’re trying to bring up a driver or you’ve got a sponsor that wants to start with a lower budget, then obviously Busch becomes a real good option.(NASCAR.com)(9-19-2007)
