It will be done when it's done. The incentive is to create something good because no one wants anything done fast and bad. That's how most AAA games get made these days.
There should never be an incentive to rush. That's how mistakes occur, that's how a bad product is delivered. I'm lucky to be in a position where I'm not so stressed about my work and am able to deliver a good product. That's how everyone's job should be.
"A delayed game is eventually good, but a rushed game is forever bad."
