The MBP is their best selling machine. Whilst there are some people like you that are waiting, there are also plenty of people like Seb and I who have bought them regardless.
Apples release schedules are a lot more predictable than some, but that doesn't mean they'll always stick to them. Without them being at MacWorld, that's a big pre-determined event that they aren't announcing things at.
It's likely to be soon, but that's likely based on the presumption that they are indeed getting the new chips.
Mac pros have been 'coming soon' for months. Minis were getting updates for years. iMac's didn't appear when expected.
But yeh, have fun waiting
