The writing seems to be on the wall. I think Tim Cook wants to simplify the Mac production line and streamline the current offerings. Steve Jobs said the Macbook Air is the "future" of laptops. Why have a 13" MBP when you already have a "more advanced" 13" MBA? The argument that the MBP is their best-selling laptop doesn't float for me. I think they want to force users to move to the MBA instead. I believe the recent leaks and part numbers. I think the 15" model will have a HiDPI display but only because it will be powered by a discrete GPU. Apple will make the 15" the only real "Pro" laptop (I mean, it's not like they sell multiple sizes of iPhones or iPads, so they'll just be doing more of the same). I know the integrated HD 4000 supports retina resolutions, but if you know anything about Apple you know they won't just barely squeeze by with performance, they'll wait until something works very smoothly and well. I doubt we'll see retina graphics on 13 inch machines until the next generation of intel chips. Meanwhile, the MBA currently supports the higher, more crisp resolutions, which will encourage buyers to get that instead. I think Apple will slowly phase out the 13 MBP like they did the 13 MB. They will continue to upgrade internals but will not redesign it. The design will continue to lose favor over newer offerings and eventually it will just quietly be discontinued from the site. There is a lot of "I think" and "I believe" in my post, and I know we won't know until Monday, but I would say at this point, don't be surprised if there's no 13 MBP redesign.
