This feels a bit tenuous. MS E3 2014 as a firesale of panic to reassure brand faithful the console was not doomed. IIRC, almost, if not all, of those titles were announced at E32014 for the first time.
Uncharted 4 was announced at the Playstation 4 Launch event, November 15th, 2013.
Deep Down was announced at the Playstation 4 Reveal, February 20th, 2013.
The Order: 1886 was announced at E3 2013.
The Witness was also announced at the Playstation 4 Reveal, February 20th, 2013.
Everyone's Gone to Rapture was announced at Sony's Gamescom 2013, August 20, 2013.
EVE: Valkyrie seems like it was announced to be coming to PS4 back at Gamescom 2013, August 20, 2013.
No Man's Sky was first announced in December 2013, without any platforms being mentioned.
Did I say a bit tenuous? I meant completely disingenuous.
