No,
Letting go of Killzone would mean losing the market share in the FPS genre that Killzone has gained through the last 2 iterations selling around 2 million plus. Obviously the quality of the game is dipping through every new Killzone game, though as long as the sales stay consistent around that 2 million Mark and Sony is able to keep the game profitable no issue.
If Killzone SF sales around 2+ and is profitable keep it, if not toss it out the door.
I am very disappointed about the newest iteration of Killzone of won't be buying it until bargain bin cheap. Though letting it go would be losing 10 years of work.
