The Avalon chips, if they arrive and start hashing for the team, will serve two purposes. They will boost shareholder confidence and put a few satoshis in our pockets, and they will give a boost to share price as ripples are sent across the community. It may well be true that the Avalon chips never make their money back, who knows, but you can't place a value of the two points I've just made.

Update 16th August 2013: The Caterpillar team have had a meeting and in light of the currently exponential increase in network difficulty and the continual delays regarding the Avalon chips come to the conclusion that it will not be possible to ROI with the Avalon chips, and have hence decided to cancel our project based around these chips.
This decision was not taken lightly and it was with a deep regret that this decision was reached. I currently have the components to build a single board with 7 chips and will be looking for 1 more sample chip, if anyone has one, so that I can build one board with 8 chips to prove that the design works. Once this has been completed I'll upload my design files to github under an open hardware license and will not be touching anything Avalon in the future.
Anyways just putting the info out there
