So I'm a bit late with this (since someone was a bit trigger happy...) but here is my opinion on Sonys conference.
Infamous DLC: Wasn't expecting it to be about Fetch, could be very cool, still hoping for some new powers
Entwined: I don't wanna shit on some peoples first work, but honestly it just didn't click with me at all
The Order: RAD just doesn't seem to be able to demo this game right, the atmosphere and graphics were great, but the gameplay was just too scripted, don't get me wrong there are passages like this in games like UC for example and they don't bother me at all, but I think they should have chosen a better demo for this show, even if they wanted to show the halfbreeds. Well at least I was right about the february release.
LBP3: Now this was awesome to me, not necessarily because I'm a huge LBP fan but because Sony managed to show a 2014 retail PS4 (and according to Amazon also PS3) exclusive at their press conference that wasn't expected, there were some rumours but it wasn't like we totally knew this was gonna come. Oh and I loved their enthusiasm during the presentation.
Bloodborne: What is there to say that hasn't been said? The fans will love and if the March 31st release is actually true (which I doubt) then that would mean a terrific first quarter of 2015 for Sony.
Indies and stuff: ABZU looked interesting. No Man's Sky first on PS4? Awesome, that game looks very cool. Overall the indie goodness continues. When they said Suda51 I was actually hoping for more info on Lily Bergamo, can't really make much of the shown trailer for the new game.
Destiny bundle: The white PS4 looks so awesome, I have no real interest in Destiny but that thing is so pretty, should sell a ton.
TLOU RE: release later than I thought, the trailer didn't really show very well how the game would look better on PS4, still cool trailer. Not sure if necessary to put it in the conference, looking at Amazon I think Driveclub could have used some exposure during the show.
UC4: Not much to say other than I nearly got a heart attack when the twitch stream just crapped out on me and left me thinking that there would be no UC this year. Trailer is very suspenseful and god is it pretty, the difference between Drake on PS3 and PS4 is huge.
Other things: I found it extremely positive that there was no GoW Acsension or Beyond Remaster. On the other hand it is of course negative that was no TLG and I still think that they have show it this year or otherwise their comments before and during E3 will just look stupid. And of course the whole PS Now and TV stuff was just dreary and went on for too long.
Overall I have to say though, that I'm very satisfied with Sonys showing, much better then the internet led me to believe it would be.
