Well, i don't think it was unexpected at all, in fact i was expecting some bear greed. A lot of people just sell to rebuy cheaper, all short term bears here are just long term bulls.
I wish someone push the price to 1000$ spending 20mil$ in one move after a severe dump, lefting all bears that sell back at 128$ with no coins to purchase at Gox.
It was completely expected, the only surprise was that it didn't happen sooner.
I think someone overplayed their hand pushing down to 128.3 though. We'll see, but I think that the bottom for the weekend won't be much lower than that.
