I have to say that those new shots seem more likely to be real game shots of PD0. I think the first one looks like a cinema shot, but I think it is using the realtime graphics. I am not blown away by the new shots, but I am definately pleased, and I have new faith in the project.
I don't care if the original team is gone. The original team left enough blue prints to make a great sequel, and with online play Perfect Dark can beat out Halo 2 as the best multiple player experience ever. Which, isn't that hard, because Halo 2 really isn't that great to me.
I hope they include all the original levels from Perfect Dark, so we can relive our favorite moments.
