As big a fan of Perfect Dark that I am, I want MS and Rare to push it back until atleast the spring. Sounds like the game could really benefit from that time. If you've already sunk this many years into the game, you might as well keep it back until it's polished up and the way they want it. No use rushing it out. There's more than enough great stuff to hold us over until the spring/summer.
They could do so much with another 6 months. I want the game to be the best it can be, even if that means having to wait a while more. I look at how polished Kameo is, and I know Rare can make PDZ great, given the time.
