but nearly all those referenced Playstation Games got announced as Ps4 Title over the past years. Coincidence??
And if really was only about the PS history: Why no Spyro? Ratchet ? Jak ? or other signifacnt Playstation references of the history
Apart from Parapa, Crash and resistance there is afaik no easter egg left which didn't become a ps4 title
PS: maybe there is a horizon reference in that video
I think you're looking too much into this (though that's a feeling I can empathize with)
Here's my breakdown
The third party references (EXCEPT for Street Fighter) are too vague to mean anything. FF and RE are both things that for some people = PlayStation. They're also big series for both publishers so surprise surprise they're also getting new games. I'll give ya SF5 because of the whole PS4 USF4 business (despite how that turned out). Also around 2013 it was thought SF5 was to be released in 2018. The SF5 announcement happened the following year (and set to be released earlier than the previous date, with funding from Sony now)
Last of Us, Beyond and Tearaway all released in 2013 (in June, October and November respectively) so it's not a surprise they got advertising references in the trailer, which was also in 2013 (Tearaway is specifically the Vita version too). TLOU and Beyond were releasing late into the PS3's life and might have been missed out on without ports to PS4 so that was an obvious call. Tearaway getting moved over to the PS4 was also to let more people experience it too.
Note that other recent remasters like GOW3 and Gravity Daze 1 (which coincidentally weren't originally released in 2013) were absent (or were absent from your post anyway). I'm gonna have to call coincidence on that one if they weren't in the trailer at all.
Uncharted is obvious. Ico is too vague to be a reference to TLG specifically. I will give you Heavy Rain (and Beyond too).
We'll have to see on PaRappa, Resistance and Crash. My money's on PaRappa since NaNa-OnSha have been interested. Resistance may be a fanservice thing (maybe someone should look around and see if there was a logo jacket made/released previously) and Crash is just conspiracy bait
I think what's not convincing me is that besides the lack of other non-2013 remasters, there's also no Gravity Daze 2 or Ratchet and Clank reference (maybe on GD). In 2013, GD2 had a teaser at TGS 2013 and Ratchet and Clank movie (and later PS4 game) were also announced that year. Seems odd that they'd miss out on these but only tease stuff that was releasing in 2013, on platforms that weren't the PS4 (at the time)
So tl;dr
Last of Us: no
Tearaway: no
Beyond: maybe/yes
Heavy Rain: yes
Resident Evil Remake: no
Resident Evil Operation Raccoon City 2.0: no
Final Fantasy 7 Remake: no
Street Fighter 5: yes
Rating: Some actual stuff may have been sprinkled on there as hints but my general opinion is that these were mostly just coincidenes
