I am sure you will see a few new indie new ips and one of them might get people talking like remember we happy few in 2016 or ori in 2015? I think many expect atleast one third party timed exclusive from them. My wild guess was splinter cell from Ubisoft due to past relationship.
Hmm... I don't know to say this better without sounding like a bit of a jerk...
But "from an announcement perspective", I don't really care a whole lot about indie-level announcements. (Ori, Tomorrow Children, Drawn to Death, etc)
Don't get me wrong, I'm not an indie-hater. Plenty of indie-games are way better than AAA games, and when it comes to enjoyment of actually playing those games, I don't look down on indie vs AAA.
But during a press conference, a small part of me groans and feels annoyed when a major new IP announcement slot from first-party is for an indie-scale game, instead of a AAA game. The game may be a 10/10, but since I haven't played it and could only see the reveal, they will never move me the same way a AAA announcement moves me. Scale matters. Perception of investment matters. That extra A in AAA matters.
I respect that games like Ori, Tomorrow Children are funded, published by the first-parties and given respectable stage presence at the conferences. But because the cost of funding these games are a fragment of a wholly new big AAA game, I look at these games and think "well, of course you should publish and fund some of these smaller studio games as a publisher to broaden your portfolio. It's a given."'
But nothing beats the confidence and bravado when games like Horizon, Scalebound, Sunset Overdrive, Death Stranding are announced, new huge AAA IPs that the publisher are staking a flag on the ground, saying that they are going to spend huge money on new properties, new games and bear that huge risk.
A lot of times the way these games are announced make me groan (CGi trailer, garbage reveal, 2 years too early, etc etc), but there is still something special about an E3 conference-level huge AAA game announcement that no one expects or no one is sure what to expect.
