New miners and veterans alike, I present to you the most realistic bitcoin profitability calculator I have seen on the web.
This calculator take into account difficulty increases and should show you a more accurate overview of bitcoin mining and potential profits.

If you plot price rises against difficulty you will see there is a price rise in line with difficulty rises, so even if you can only mine a lower amount of BTC, then the price you get for them is higher also.
Nice graph, wrong conclusion.
