Some more civ5 details from a VentureBeat preview

[Robert]

The game section of VentureBeat posted a preview based on the same Firaxis session yesterday on GDC.
They offer some details from the demostration that were unknown so far.
To start with, there are special 'flaming arrow' archers, apart from the usual archers. Now the firework we saw in some screenshots makes suddenly sense!
VentureBeat continues to explain that armies are more expensive to build and to maintain, but will also last longer.

Cities will defend themselves on a fixed number of defense points. And most important, territories now have capitols, and if you take them, the entire territory will be yours. It's unknown yet if this is a different way to phrase the already known way to achieve a domination victory by only capturing the capitals of all civs, or if Civ 5 indeed includes something like state capitals.

Cities will defend themselves on a fixed number of defense points.

Does this mean that units fight with cities, and each victory takes away a defense point?

And most important, territories now have capitols, and if you take them, the entire territory will be yours.

I prefer this to cultural borders, but what will culture be good for?

Maybe it means your defense rating, rather than defense 'hitpoints'.
So if you build a city wall, the defense rating increases, giving it more chance to win a battle.
I assume it must have 'health' as well though as if it's a unit.
