Associates: Oh yeh, good idea.

Other exchanges: Oh shit, that actually is a thing, let's halt withdrawals too
Other exchanges: Yeh ok fair enough
*malleability fixed*
Other exchanges: Ok done, allow withdrawals again
Other exchanges: Nice one guys, back on the way to the moon
Mark: Holy shit BTC is so cheap right now, if only I bought a couple before I allowed... Oh wait, I am the sole force in the Gox market right now, if I just manipulated the price a little lower I could.... Holy shit this is really working!! *buy buy buy*
Associates: Hey Mark, shouldn't we like... allow withdrawals now?
Mark(+the ppl in the loop): No, there's this thing about this thing and well, yeh it's technical and... stuff so, don't allow them till xx/xx *Gets 100k USD Loan to buy btc*

Mark: Wow I have a shitload of cheap BTC, I could just allow withdrawals now and boom, profit bitch.
Prediction: Gox back up in the next month, and everyone just sweeps it under the rug.
This theory of yours is just a variation of the many theories posted, that in the end, are all hoping that MTGOX isn't a dead and bloated corpse.
Gox is dead! Bagholders left in Gox are screwed. Move on and acknowledge that the death of Gox is good thing. Everyone knows Mark Karpeles and if it comes out that he screwed so many people over intentionally by the manipulation that you posit in your theory, I don't think that there's a place in the world he could hide.
Gox is dead, accept it.
