Another reason not to order the extra modules is the power supply. I doubt the stock 3 module unit is going to ship with a power supply that can support 6 modules.
In fact, if you look at the bitcoin foundation pictures, there is a different PSU in the 4 module box that jeff has in his 3 module box. the bitcoin foundation PSU looks like an enermax while jeff's is an antec.

What if Avalon release a 55nm chip revision with the same board layout? It'd be interesting to hear how much wattage headroom the 3x20 GH/s have with their stock PSU, people that don't upgrade their 110nm boards early on might be able to use the space more efficiently if Avalon can stick with their module dimensions through their chip upgrades.
I'm actually quite curious about this as well. It would be very cool if they were able to maintain the current board layout while packing more chips on each module at 55nm..not to mention the power efficiency increase.
