PR's progress has been ungodly slow...if you just look at the time and not the amount of work they've put into it. Brushing it off is being ignorant, there has been a monumental effort behind it, and I don't think anyone can truly appreciate or understand it until they know about how they got some of the features to work (interceptors, addons, nukes, unit portraits, resources, just to name a few). Also, theres more stuff made than the models in the gallery. Its an amazing mod if only for the feats achieved in coding and modeling.
Yes, it has taken a long time to get to where they are, but they have yet to quit, and have put out a beta, which is a hell of a lot more than most mods out there can claim to have done.
As for a campaign, things were discussed all the way at the beginning, so I guess it will have to be re-evaluated, as all that is outdated by now. I'm no official spokesman, just a con from before they had a label for cons.
That was purely for a demo video, not relative to the campaign they are planning
As far as I know, he is right.
