I am sure that things like this can be twisted for the benefit of whichever platform you have an affinity to. The reality is that every game that isn't exclusive (or already available on other platforms like the Witcher 3 for example) will also be coming to Playstation.

Any game that maybe coming to Xbox first can still be 'claimed' by Playstation sites because they will (eventually) release on this platform. I am using Xbox here because they gave a press briefing this year whilst Sony did not. It would be like MS claiming Hellblade and Nier for example in previous years too.

Obviously there was quite a presence for Sony with games like FFFvii and Shenmue 3 that were at E3 and certainly coming to Playstation with no mention of other platforms (yet - if they are timed). If this is 'just' counting exclusives and 'new' releases to just that platform, it wouldn't be a stretch to see Nintendo in first - whether that counts Witcher 3 too because its not necessary to count the fact its been available for years on other systems.

It also wouldn't be a surprise if Microsoft/Xbox comes in second as they were at E3 and quite a few of the 60 games they showed are 'exclusive' to MS so its not unreasonable for them to come in second. With a few games shown by Square Enix that are 'exclusive' to PS4, then of course they could be 3rd if the majority/all PC games discussed/shown are also coming to consoles. Then it just leaves mobile/tablet games and whether they are exclusive or also coming to other Platforms.

All this states is that Sony came 3rd beating PC and Mobile gaming but coming 'last' (3rd) out of the 'consoles'. With Sony getting some 'content' in Marvels Avengers, the base game is still coming to PC and Xbox - same with the new IP's Bethesda announced (at least I thought they were) and certainly Cyberpunk 2077 will also be on PC and Xbox.

'Published' to me means that the publishing rights, the ones who will be printing and distributing the games. Sony aren't publishing Marvels Avengers, Square Enix are and Star Wars is Published by EA, Cyberpunk 2077 isn't published by MS, that's Bandai Namco (or Warner Bros in the US) so I am not 100% sure of what this article is trying to say...
