I don't see the 13" MBP sticking around much longer. At this point, the differences between the Air and 13" MBP are minimal, so I see them eventually adding a few more cores to the air, possibly giving that some of the aesthetic treatment of these new Pro's, and removing the 13" from the lineup.

It's possible the Apple employee knows something we don't, but it doesn't make sense to keep it around since there is nothing particularly Pro about it when comparing it to the new machines.
