I think by now the Mt gox funds have been released according to the @op or they are still in the process, whatever the case may be I don't think it will really have much impact on price than what we have already seen, if you have bought from that dip, you will be in profit already, between you can always split the buy position, 40%, 30%, 30% depending on the market condition, if you don't want to buy all at once.
I have checked few crypto news portal and few other blog of blockchain analysts but none of them reported about the release of funds from mtgox. In social media also no talk about this as some people usually notify about similar pattern based BTC movements or other crypto based movements.
Usually bitcoin traders react to news well in advance which might have happened this time also; like for expectation of upcoming dump from gtmox refund, traders might have booked profits/exited their positions with the plan of buying back to cheaper price levels and made the recent correction.
