By my estimation, at the current rate of ~6 blocks/~550 seconds, we've got about a week to the next difficulty level, give or take.  Has anyone charted their USD per month, day, hour?  I'm curious about how the reward in USDs has followed the increase in difficulty and decrease in the number of bitcoins rewarded per miner.  My 615 Mhash/s gets me about 0.27BTC/hour, and my BTC/hour is going to decrease when the difficulty goes up.  At the current exchange rate I'm mining ~ $0.35USD/hour.  I wonder if the exchange value of BTC/USD will remain such that 615 Mhash/s still returns ~ $0.35USD/hour.

I created such a graph but it's been not updated since March because I couldn't find the trade data.

I'll update it as soon as I get the data.

In long term, the mining income decreased in USD, i.e. difficulty increased faster than BTC/USD. Each jump in profitability resulted in miners extending their mining operation and difficulty going up.

edit: Updated thanks to bitcoincharts data. With the recent BTC increase, the mining income rose but it's still far below the levels of the small stabilization at the beginning of the year.

That is an AWESOME graph.

Thank you so much for posting it!

It really helped me put my mining rig decisions in perspective.

Thanks for that graph!
