It's very difficult to predict how much money these will make as it's unknown by the time you get one how many other ASICs will ship. If you look at https://bitcointalk.org/index.php?topic=89685.0 https://bitcointalk.org/index.php?topic=89685.0 these are preorders for BFL ASIC that people have reported. So at the current difficulty you would make $220.35 / day with a 66 Gh/s Avalon. If you look at predictions people are throwing around though on what these BFL orders will do to the difficulty (https://bitcointalk.org/index.php?topic=89685.msg1218884#msg1218884 https://bitcointalk.org/index.php?topic=89685.msg1218884#msg...) then your $/day would go down to $11.42. The question is will BFL ship on time and how many units will they ship. They claim to be shipping their first batch on the week of Feb 10th. This second batch from Avalon is said to be shipping March 5th – April 5th, 2013. So if you believe BFL will ship before then, then the difficulty will look very different by the time you get your Avalon.
