which you're going to access over wireless?
USB2 is faster than your wireless signal, so no need for thunderbolt.
You still missed the point about gigabit Ethernet and attaching a TB raid to the base station.
Also if apple REALLY wanted to drive TB sales it would be smart for them to put it everywhere and then sell and/or promote the heck out of 3rd party TB docking bars.
Imagine a AEBS with just two ports...
First would be for connecting to the existing Ethernet and the second being a TB port.
Developers could make any combination of TB port bars...
6 Ethernet ports for those who want to have the AEBS act as an Ethernet switch
6 Ethernet and 2 or more USB2 ports + audio out ala AirPlay
6 Ethernet and 2 or more UBS3 ports or SATA6 ports or FW800 ports
Plus they could do it in a elegant way and loose the need for different permutations of AEBS and 2TB time machines and 3TB time machines and airport express devices.
1 AEBS is all they'd need to make and then docking stations with all of the various options in docks that would have similar shapes.
The bonus being the docks would be attractive to not just AEBS owners but also MacBook airs, iMacs, MacBook pros, Mac minis etc.
The extra bonus being the AEBS would have far less components so it would cost less and be easily upgradable without the needless replacement of all the ports and components usually found in a AEBS or a time machine unit.
Seems like a great deal with everyone coming out ahead.
