Apple might be anouncing something tommorow at this Final Cut conference, so I would give it a 5% chance of an update by the end of Macworld. I am probably gonna order a 2.6ghz MBP tommorow if nothing happens. If the rumors of Penryn being delayed til the end of Feburary-March are really true, then I wouldn't be surprised if Apple dosen't update the MBP's til May when the new chipset is going to be released. Also, I suspect that the next update to the MBP will be a case redesign with the addition of the MBA's Keyboard. Could very well look the same case wise but with user replaceable HDD, magnetic hatch, and the new keyboard.
