As someone who has been worried about the Mt Gox coins hitting the market for a long time, this is the reason why bitcoin keeps dropping.

There are just too many coins going to hit the market in a short period of time to sustain these high bitcoin prices.

Many people also requested their mt gox coins in cash, this means the settlement lawyers will have to sell coins to get cash to pay these people.

Price will stay low until the settlement coins are distributed.
