Well, I'm hoping that after that they'll still be able to do something new. Ending it there would feel... less than satisfactory. Season 10 did a nice job of wrapping everything up, and the series could've even ended there. So in the scheme of things for the whole series, it'd feel like "Happy ending yay it's over - oh wait we gotta win this war first - okay NOW it's over". It'd just seem too abrupt for me.

Also Miles has only just begun writing for these seasons. I doubt he wants to stop so soon.
