A very poor showing from Sony this year. Why do I think this?
I believe anyone really interested in the games shown there would be getting them regardless if they saw the E3 event or not. Sony preaching to the choir mostly. Sony gave those not already interested in the games a reason to get interested. Kingdom Hearts 3 was the exception as that trailer was quite good. All the rest were just overly long with very slow buildups. That first 20 seconds of a an initial reaction were wasted.
Also the music and chatting didn't do much to help. Most of the Sony fans I know were stratching their heads as to what the music was and it only clicked once the gameplay footage appeared. That kind of pre trailer music needs to be totally iconic so every fan instantly gets it.

Look at this video around the one minute mark. Totally iconic music. Everyone in the room totally got it. The piece of music told everyone what IP was being announced. And because it was "big news" everyone knew it was Diablo 3. Sony could learn how to use music in keynotes from Blizzard.
Sony would have been better to just do a fully digital event with only the trailers and kept all the drawn out gameplay footage till after the event.
So what games do I think would interest someone who is on the fence and not already wanting to purchase the game?
Kingdom Hearts 3 - The 1+2+3 box really helps sell that idea
Spiderman - Possibly. The trailer + gameplay was still overly long and poorly paced but was not too bad.
That Kojima game - Death Stranding?. It asks more questions than it answers which is quite appealing.
Every other game just felt like a stealthy killing spree. The only differences between them all is where and how you use stealth to kill everything.
I give this keynote/event a
C.
The fans will like it but anyone not already a fan will be hard pressed to find much of that interesting.
