Politics in M2TW

[Krosh]

I just read a post in the MTW forums that I found very interesting. In the game it was possible to "inherit" kingdoms if a kingdom lost it's king, all of his heirs, and if one of their princesses was married to one of your family members. So my question is if it will be possible to inherit entire kingdoms by brokering for a princess' hand in marriage and then systematically killing of the rest of their royalty in M2? If practices like this continue in M2, then it would be a nice twist to the game when compared to how Rome only allowed total victory through conquest.

Here's to hoping politics and diplomacy offer a valid alternative to total conquest.
