It's not just Epic, GPG's been doing the same thing with Supreme Commander (I know, I report on this stuff on a
shamelessly pimped website myself). Every interview has the same answers... three teams with unique unit designs, the ability to scroll out from the "tactical" view to a satellite-style view seamlessly, and so on. The real meaty questions always get side-tracked generic answers or simply "we can't answer that at this time," which is very frustrating. At least we always get a couple new screenshots almost every time, although sometimes it's just the same **** different angle approach.
Anyway, the point is, like someone said above, that both companies don't want to spill the beans too much before E3. It
is very frustrating that they recycle the same information constantly, but you do have to consider that the people like us who follow games closely are the only ones who are ever really going to notice. Most people just don't care until the demo release or a month or two prior to release, even with all of the E3 hype. They'll only care when they have something they can actually play and not look at or read about, and that's when the real information will be unleashed.
