We're still a ways off from release and so very little concrete information has been released. I can tell you that, from what I see in your post, you should be pleased. Among (a lot of) other things, Spycraft Third will be able to dramatically shift the tone, flavor, and mechanics of combat, gear, and a host of other things, so that realistic game will be perfectly doable. So will camp and everything in-between. There will be a baseline, which is a lot closer to modern (Daniel Craig) Bond than anything else.
