Maybe the release of 100,000 BTC will not be that damaging.
If Bitcoin is released with the amount of 100k , of course the crypto market will be red like the sun that cannot be seen directly. That is, it has a huge effect on the crypto market.
Nobody wants to buy fearing MtGox holders will dump their 9 year forced-hodled coins.
Maybe MtGox won't let go of all the Bitcoins he owns. Big investors don't brutally destroy the market by selling all assets in an instant, they prefer to create more attractive wave charts, not waterfalls.
