Ew... 4am.
Looks like I'll have to catch it later, unless I have insomnia, which can happen before Bioware games/DLC/conventions sometimes... 
The topics:
Dragon Age: Inquisition --> Almost certainly. It'll be less than 3 months until release, so August-September should be the big infodump time for most of what they have left to announce and discuss. Want to know if Solas is a LI? Maybe you'll find out. Want to know if 'insert achievement list rumor feature' is a thing? Maybe you'll find out.
Nightmare/Spark/Shadow Realm?/Shadow Lord? --> Almost certainly. It keeps being mentioned for Gamescom. We don't know the extent of information coming though, or even what the nature of this is. Is it a larger Bioware umbrella thing of unknown nature? Is it a small browser game or mobile app, just with viral marketing attached? Is it a major game/franchise that they're starting to unveil? Is it somehow all of these things at once? Is it MMO? Is it SP? Is it MP?
Who knows?!?! Lets see what they have to show us.
'New IP' --> Possibly. So far from Bioware employees' words, the above project isn't the same as the New IP being made by Bioware Edmonton. If this is totally true, then we still have no information on it, but there's the chance of getting something (even if more of an off-hand quote from a dev) regarding it.
Damn It Its Not Mass Effect 4 --> Possibly. While most would agree that N7 Day is a great time to unveil Mass Effect news (or at least at some point in November - they may wait for Inquisition to be released first), Gamescom is still a possibility. I'm not saying it'll be big or small or anything, but something could happen, especially if they are taking 2 hours.
But this is EA. So 1+ hour of this may be sports, and 1+ hour of this may be straight shooters. So... yeah.
I'm only going to prepare for Inquisition and 'Nightmare', and be very pleased if they decide to go beyond that.
