The 150K at 35 cents is what is keeping the preopen down, and has effectively stopped the preopen sentiment that was beginning to build. It's there for that reason - so will either be pulled or left to go through to facilitate some additional cheap sales from nervous nellies.
My guess is that it would be pulled however - if it was a serious player they would be stacking the sell side more convincingly. Should see open of 40.5 then up from there is my guess.
