Yes there are many on BTC-e who has orders in $100-$300 range that never got filled in, it happened so fast that i think only a limited amount of people actually got to buy it at those prices before it shot up to $500+
If someone had orders at $200 that went unfulfilled, then there is no good reason at all why the price should go below this. The fact that it did, proves that these trading platforms (BTC-e and Bitfinex) are hooky, with front running facilities clearly being provided to selected parties.
For example, my 90 days+ old buy order @503 on Gox has never been fullfilled this morning, but I'm sure it will tomorrow
