First of all: Awesome chart! A few things that need to be updated, tho, which all have the potential to change the general outlook of the chart:
1) The Avalon team has confirmed it will run at at least 66GH/s, rather than 60GH/s. 10% speed boost? Hells ya!
2) The Avalon will retain it's $1299 price even after the pre-orders have finished. They will
NOT be raising their prices to $1999 like they originally said.
3) The Avalon has confirmed a 400W draw, but they said that that could go down further by the time they ship.
All of those facts can be confirmed in the first post here:
https://bitcointalk.org/index.php?topic=120184.03) We dont have exact power numbers for the bASIC, but 300W is a little high. That number about the 1000W PSU being able to drive 10 bASICs doesn't clarify whether that's the 27 or 54GH/s units, but I'm inclined to think the second. I'm guessing 1000W will power either 10 27GH/s units, or 5 54GH/s units.
End result: Increase the Avalon hash rate, decrease the Avalon price, and swap the Avalon and bASIC power numbers.
