When it comes to map size and pacing what I personally like to experience is variety.
I'd agree with UV in that having every map involve a situation where you have to hunt down that last alien which is hiding in the corner would quickly become tiring.
But I think it's the same when every map is close and tight with limited space to actually explore your surroundings as it is in the modern Xcoms.
For me what I'd like to see is a bit of both, some short intense firefights, but also some bug hunts where you do have to track down an ellusive foe... Or even the opposite, where you have to avoid and hide from a foe which clearly outmatches you.
With squad sizes being larger in PP than Xcom, I'm hoping that, on average, it will lead to larger maps.
From what JG was saying it sounds like missions will have multiple objectives, to that end, would the player even need to hunt down that last creature? Could they not just leave the map if they were inclined to?
Whilst on this subject, I think one of the aspects which peed me off as much as anything with Xcom was the fog off war. I've got all this advanced technology on my hands, but I don't have a radar image, or even a map of my local area so I go round every corner blindly revealing all the black space. Really?
I think Laser Squad got this aspect of the game bang on right... Show the whole map to the player from the offset (or at least the building structures) but hide anything that lives until that being comes into your line of sight.
Laser Squad also got it right as far as map designs went imho. There weren't many, but the variety in them along with the choice of starting locations made them infinitely replayable. When I played Xcom I just felt like every map was more or less the same map being repeated, the outdoor one, the four building block one, the flyover, oh look it's the outdoor one again... Sure, they're pretty but, oh look it's another outdoor map...
