Seems like it "has't got"s are down to 2+Gb of Ram and GB Ethernet, but I'm not sure thats really that important, for allot of applications other than desktop PC it's processor is overpowered.
Whilst it seems reasonable that a version that will support faster bus USB3, GB Ethernet is in the pipeline, its now pulling 2+A at 5v now, so your likely looking at a 15 Watt device that is not going to last long on small batteries
I think a more mature line up would include lower power, lower profile units (which seems to be the plan) for IOT and low power robotics and control, and likely sell a lot of units, vs a higher power unit which starts to compete, once you add a screen and peripherals with budget pc and similar commercial devices.
To me the family aspect of it becomes more important, we know there are similar fruit inspired products that trump the RPi on features and performance, if Raspberry want to grow the commercial aspects low power, low cost, low footprint, customisable is the way to go, rather than (or as well) as micro PC.
From what I understand from the Element 14 Launch that is pretty much what they are doing.
