Wait until the 26th-27th thats the next rumored event. However it is a small possibility that these will be updated sans event(a la new iMacs). I bet that if there is a media event they will be updated as an after thought.
It would be nice to see it tomorrow but its unlikely. I work in the mall 2 doors down from the apple store and I often talk to the sales reps there one who im a little more close to told me the last week of jan he also said look forward to seeing the old macbook pros specifically 13" being on sale. i plan on picking up the new one whenever it comes out my guess would be jan 27 tho
