I found this bit particularly interesting...

"Cyrodiil is not simply about fighting over Keeps and killing the enemy.  It's an economic war as well.  When a wall is destroyed, it has to be rebuilt, and rebuilding it costs gold and time.  Your hard earned gold and efforts come into play not only keeping your lands safe and establishing beach-heads in enemy territory, but also hitting the enemy in the wallet! Let's say you're a small group and not enough to take a keep over...you can setup some weapons and destroy wall sections that the enemy has to rebuild and spend gold or alliance points to do so!"

Edit - Also this...

"Cyrodiil is very very large!  On foot it would take you roughly 20-30 minutes to cross it from north to south."

It's very interesting that war has an economic element. However if there is no reason to hold the territory alliances will not invest gold to repair or mantain keeps. Hopefully it will not be too easy to take a keep when unopposed also, otherwise the upgrades could become useless also.
