I'm mining 4 systems each system over 10,000 primes per sec and Haven't found a block sine midnight. 
HP2
Anyone having these issues?

Pretty much the same issue. The difficulty is now very high and due its exponential nature it means that blocks are very hard to find.
As Primecoin nature is different than other coins I wonder if it's even possible that diff goes down and make it profitable again. Any thoughts ?
I am willing to bet difficulty will be heading down soon, its no longer profitable for VPMs
Yes, diff should go down if VPMs in not profitable anymore but, my question were "is that possible?" Can the primecoin diff go down ?
I think so, sure, why not. The dev (sunnyking) told days ago about the diff still catching up, and that is was "expected" behaviour. Diff is indeed still rising. Yes, there is a point where diff would drop, but it's not now. (correct me guys if this is wrong)
