If they do phase out the non-retina MBPs, that means none of Apple's laptops will have ethernet ports. On a "pro" machine, for the sake of shaving off a millimeter or two.
High-resolution displays are great, but Apple's fetish for thinness is causing some unfortunate side effects.
Thunderbolt to GigE adapter is only $20 or so. I don't consider the reduction in thinness in exchange for the removal of a port I rarely use to be that unfortunate.
At least for $29 you can get the Thunderbolt-GigE adapter, I keep one attached to the patch cable in my bag.
I appreciate the speed and flexibility of TB and think it will pick up momentum as more and more people end up with ultraportables and other thin machines.
This really bothered me when I found out. I was in a coffee ship working and was forced to pack up my back every time I needed to use the bathroom. The two solutions out there, one from kensington and the macbracket, are poor substitutes for having a kensington slot.
