What will happen to the yellow jersey today?

There's some discussion about CSC's decision to abandon Zabriske yesterday. Given the number of riders they had, they could have allowed 1-2 riders to stay with him and ensure a better time, etc. Not very sporting of the team - although obviously not the riders' fault but a "management" decision.

So, will Lance try to keep the jersey today, or will "Gorgeous" George be wearing it after Stage 5?
