How mutch more power or time (for that matter) can the new led 15" MBPro save compared to the outgoing model? 1hr, 2hrs of battery life...more??

According to Macbook Pro LED Details, "The 15" LED MacBook Pros extends battery life 30-60 minutes when compared to the older MacBook Pros."

so would it be safe to say that the new17" also saves some amount of power compared to the old model since it also uses the Santa Rosa chipset?
