As of right now we would need around 250 GH/s to reach target blocks and networks running at around 50-60 at the moment.  So we will see blocks just under an hour apart and every 8-9 hours we will get a difficulty drop that will push profitability higher and attract more miners.  As we saw a rebound in FRC valuation back to the .0004 it had been at just before the hash-crash the profitability is right back at near 100% relative to BTC.  Price stability has been quite impressive over this difficult period with a drop of only about 25% which has now been fully recouped.
