Halo 2014 Dedicated Servers?

I was watching the last 20 minutes or so of Microsoft's E3 Live Stream when the Halo teaser came on. Woohoo! Another Halo. Anyway, someone from 343 came on and spoke a little on the topic of the new Halo for the Xbox One. She said that Halo would take advantage of cloud computing, dedicated servers, and something else. I couldn't catch the rest after I heard dedicated servers.

The term "dedicated servers" should cause people to take note when it comes to console multi-player right? She kinda glossed over it in her speech, but it seems like such a big deal.

Did anyone else catch this in context, and do you think she was referring to multi-player support or something more like other game processes?
