Yeah. I have a feeling they have cut out some huge battle at Haven before the fight with Corypheus. It would make sense because unless everyone but you and the 3 you pick to go with you, aren't doing anything, why wouldn't they just follow you up to the fight with Corypheus. Though from listening to it, I got a DA:O vibe from it. Felt like I was listening to the last words with your companions again. Probably why it was cut.
Yeah, sounds to me more like the final battle for sure. They specifically say demons, which is what would've/should've happened when he re-opened the breach just like it did the first time around, companions on the ground that are taken along with the Inquisitor stay behind to fight the demons flooding out attacking everything, Inquisitor (and presumable) +3 go up to deal with Corypheus.
This also leads me to believe that there was supposed to be the final goodbyes on the battlefield, which means (in theory) there should be audio floating around in the files containing such.
