It's way too early to tell, and if we're really averaging 6.13blocks / hr then it will not likely decrease. This turn of events is not at all unexpected though, a huge boost in price lead a huge boost in hashing power. A huge drop in price effectively curtailed such a continued expansion, but it's much harder to get out of mining than it is to get in. So we see a bit of stabilization.
My worry about the current stabilization is that concept known as stagflation. Interest and demand taper off, while bitcoins continue to be pumped into the system. Hopefully the new stabilization in both hashing power and price ("stabilization" obviously) will attract more businesses to accept bitcoins as payment. Without the dreaded price swings, it should be more business friendly for those looking at balancing the books.
It seems most people are in agreement that the software is simply not ready for prime time yet. That is, you will find a lot of smaller businesses and even some urban shops taking BTC (as with the recent CNN story), but a broader adoption will not happen unless the security issues are ironed out. Expecting mainstream consumers to encrypt their wallets is simply not realistic.
As for the difficulty, it is rather amusing to see a potential stabilization after a month or so of chicken little calls for dramatic 50+% increases to the moon.
Well, I suppose that I agree with the idea of prime time delay, but it takes basically no infrastructure for a shop to at least open up the doors to accepting bitcoin (unlike the billions of dollars required to enable the smart phone CC readers which are coming out), so I see no reason why a shop couldn't at least potentially accept bitcoin as payment (especially online stores). Doesn't have to be an overnight thing, but the more places that are at least willing to accept the coin the better it is for bitcoin, and the faster you will see developments like enhanced security features.
I agree on the difficulty calls, I've been arguing with people for weeks who claimed that because between may and june there were huge increases that would always be so, even to the point of creating spreadsheets with future difficulty predictions > 1 BILLION. I had to hold myself back from actively calling these people out as things started to smooth over. I don't know the future though so I may end up just as wrong, so for now, I'm just enjoying the current state of affairs.
