I don't know how the matters stand at the moment, but in August there was a transactional glut, i.e. there were a few thousand unconfirmed transactions that didn't get confirmed in time (up to 50,000, if I'm not mistaken). I got caught too, my ~1 BTC transaction hadn't been confirmed for 2 days. I guess it was a deliberate effort by miners to stimulate the price, since I saw a lot of new blocks with only the miner's TX in them...
Therefore, it is hard to predict what the miners can be up to
That was because the stresstests. Someone created piles of junktransactions with a sligthly higher fee than legit transactions so that miners included the more expensive transactions and normal transactions got stuck. The problem was not that too view miners exist but that each block only can hold transactions worth 1mb of data
This is what I had been told. But it's cold comfort, given that I got caught personally (for 2 days, Carl!) and generally don't believe such stories, lol. The theory of the more expensive transactions crowding out normal transactions doesn't hold since it fails to provide a viable explanation for empty blocks...
