I just updated 10.6.8 and now my battery dies rather quickly after a full charge.

I have the new early 2011 MBP before it would last for hrs now it last a half an hr before it hits 70%, anyone else having this problem?

When did you last Calibrate your battery?
Here's a nice guide from Macrumors.
In Terminal type:
ioreg -l | grep Capacity
    | |           "MaxCapacity" = 11317
    | |           "CurrentCapacity" = 11291
    | |           "LegacyBatteryInfo" = {"Amperage"=0,"Flags"=5,"Capacity"=1131$
    | |           "DesignCapacity" = 13000
As an example, mine was manufactured with a capacity of 13000, now it can get to a maximum 11317, and currently it's charged to 11291. You can also hold Option and click the battery icon in top right for your batteries condition. Also the cycle count is in System Profile under Power.
