I sometimes get confused about Sony's 1st vs 2nd party developers, especially since a 2nd party may work on the remaster of a 1st party game. So I'm just going to focus on games published by Sony for the PlayStation 3, 4, and Vita, counting only retail games.
The PS3 had a total of about 120 or so retail games published by Sony, including "shovelware" games like "SingStar Apres-Ski Party 2" and the like. Of these, a few of them were remakes, remasters, and/or compilations of older games, including 2009's God of War Collection, 2010's Sly Collection and God of War Trilogy, 2011's Team Ico Collection, Ratchett & Clank Collection. and God of War: Origins Collection, the 2012 Jak & Daxter Collection and God of War Saga. Yes, that was a lot of God of War. Still, that was a total of about only eight games out of 120, maybe 7% of retail releases.
The Vita has had much less retail games, especially when discounting co-publishing deals and regional exclusives. Let's say about 35 total. Its library includes 2013's Jak & Daxter Trilogy, 2014's God of War Collection, Sly Collection, and Ratchett & Clank collection. That is only four games, but considering the high number of ports from the PS3 and other platforms, including PSASBR, Minecraft, Epic Mickey 2, and Borderlands 2, Sony gets its name as Publisher on a lot of ports of games to the Vita.
The PS4 has just 12 retail games from Sony so far along with 8 confirmed upcoming titles. Of these, The Last of Us is the most obvious example of a Remaster released so far. One can also argue that Minecraft, published by SOny at retail, also qualifies, seeing as the PS4 version is an expanded version of the PS3 version. And coming up, we have God of War 3 Remastered, Tearaway, and the Uncharted Collection. That is a solid third of Sony's announced upcoming retail games.
For comparison, it's time to look at the competition. The Xbox 360 seems to have had virtually no remasters from Microsoft itself, and even the XOne hasn't had that many. Of the roughly 20 One game released or announced by Microsoft, the only remasters or collections have been the Master Chief Collection and the arguable Minecraft version for the One, since like the PS4 version is based on an older iteration. That's significantly less than Sony.
Nintendo is a bit odd to judge due to their strong split between console and handheld games. The 3DS has had about 50 retail games from Nintendo. Of these, three were remasters of N64 games (Zelda and Star Fox), two wer Wii ports (DKCR and Xenoblade), and Pokemon got a GBA remake. THat is a fair number of remasters, but none of these were collections.
On the Wii U, 30 retail Nintendo games have been released or announced. Of these, only Wind Waker HD and Wii Sports Club are easy to call remasters or remakes. You may include New Super Luigi U, but that was also DLC, so I dunno.
Love and tolerate.
