The projected difficulty for late February 2014 is somewhere around 3 billion on the low side and something like 5 - 6 billion on the high side. 312 Ghs at that difficulty and the current exchange rate for bitcoins would yield about $425 per week with the yield dropping about 15 - 20 % every 12 days or so. The yield for 6 billion difficulty would be about $200 per week. That weekly yield would give about $20,000 or $10,000 earnings WITHOUT any further increase in difficulty which will never happen.

What causes the yield to drop about 15-20% each 12 days? The difficulty increase?

Yes it increases as time passes by and more coins are in the market.
Honestly, Bitcoin mining is not profitable anymore. Any coin's mining returns good ROI in its initial stages.

Thanks everyone.

So how do people intend to stay in the game? I mean, what kind of a rig would give enough GH/s/J and not cost too much to eat into the revenues?

Some people are mining other coins like LTC. Sometimes they are more profitable, because you can sell them for Bitcoins and gain more BTC then mining it.
