They might not be able to do that if they have the same power consumption as it would reduce the battery size significantly.
I suspect they will, otherwise the 13" would look like it's taking a step back but I prefer non-tapered:
No optical as you can buy a cheap external (even Blu-Ray).
USB 3 to replace FW800 and ethernet (4 ports on 15", 2 on 13").
Thunderbolt x 2 on 15", one on 13".
They have to go with 256GB entry SSD on the 15". Removing the optical saves them $100 and with SSD being around $1/GB, they can get 256GB in the entry model. This means no need for an HDD and they can easily have a BTO option for 512GB for $300.
The alternative is to simply get a USB 3 SSD or portable drive for extra storage. It will only be a hardship for 1-2 years as SSD prices drop.
I expect the 13" slim machine will take the place of the Air and Pro - just one model. That would suggest it has to be tapered with Ivy Bridge dual-core (4-thread) and IGP.
The 15" still quad-core with either NVidia or AMD dGPU.
I think high-resolution displays would add too much cost during the transition so same resolution as we have now.
I personally think the laptops are incredibly fast so I don't expect the CPUs to jump up a huge amount in performance but focus more on lowering power consumption and heat output. Look at the current one rendering Cinebench:http://www.youtube.com/watch?v=9770So2nZ0Q
That's only 1/4-1/5 of some of the highest-end desktops:http://www.cbscores.com/
Not that they should stop pushing the performance but it's really not the bottleneck ATM. Move to SSD, put in lots of RAM, drop the power consumption and heat and then start bumping performance again next year.
