nice post. Given that the BTC-USC exchange rate at break even and the starting difficulty are perfectly correlated it would make sense to normalize the graphs against that. Which means a plot: Days to break even VS. ($breakeven / average or starting difficulty)
Actually what would be even nicer is to use some combined efficiency measure on the x-axis. Right now the efficiency factors are distributed across different graphs.

Plan for the Worst and Hope for the Best? I'm going to run my own personal numbers based on the worst case scenarios, but I am more than willing to be proven wrong.
I would just line up everything fairly. 
Take what the companies have let out, and use those figures, rather than only doubling Tom's.
Going by that logic I would remove bASIC completely! Both 200 and 100W are the same rough numbers.
I'm suggesting 100W is FAR more likely a number since that is how the detail was presented.

Why would you guess the worst?
I never actually saw Tom's post that gave rough power numbers, so I'm going off everyone else's claims. As far as why I might come across as a pessimistic, what's the saying: Plan for the Worst and Hope for the Best? I'm going to run my own personal numbers based on the worst case scenarios, but I am more than willing to be proven wrong. 3) 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.

He accidentally said 54G was 100W. Deleted reference to it.
Accidentally posted 10 bASIC units would run on a 1000W PSU.
I think it's pretty safe to assume 100W is the aim for bASIC.
60W is the aim for BFL SC 60G.
400W AVALON.
Thanks for your comments, everyone.
Yes, I think that somewhere in transcribing data I swapped bASIC for Avalon. I also didn't know that Avalon was stand-alone, or that it's hashrate would be increased. Since the first two of these are errors on my part I'll update the figures and post an update tonight.
Please keep posting corrections and any updates to device specs - I don't have much time to spend reading relevant threads.
End result: Increase the Avalon hash rate, decrease the Avalon price, and swap the Avalon and bASIC power numbers.

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://bitcointalksearch.org/topic/announcement-avalon-asic-development-status-batch-1-120184

General consensus is basic 54g is 100W.
You missed another post where the flickr account said it and was then deleted. It may have been wrong, but it's a better confirmation than the psu and assuming the worst for your graphs.

Also, the price and hashrate on the Avalon is wrong, it's $1300 for 66GH/s, with a maximum power draw of 400W.
Great work! Life is full of surprises, though - and in this case surprises will turn out to be critical to the outcome. It will all make sense in retrospect.
On the site it says this 1000 watt psu will power 10 bASIC units. What it doesn't say is if that is the 27 or 54 Gh/s unit.

Tom hasn't released his power usage yet unless I missed it. Where did that 300 watts come from?
Excellent work!
You used two of my favorite things when writing up an article; Math and Proof of Work!
I actually didn't know there was such a disparity between device wattage of BFL, Avalon, etc. I'm sure I've seen it around, but it just never stuck with me. I'm glad to see everything compiled into one doc!

I've written a short post detailing how to estimate an ASIC device's yearly earnings, the time it will take to recoup the initial cost, how long you can can expect to mine profitably with a given device and more. I won't repeat the entire post here, but I've posted a teaser chart below. Post your own analyses and chart, and help fellow miners figure out which device they should purchase. I look forward to your comments and suggestions either here or at the blog.
