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.

Nice, however incorrect, as it doesn't factor in price rises of coins. 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.
