From what others have speculated, Sony's strategy seems to be focused on just what's immediately coming within six months or so and dedicate attention to it. They also seem to not want to reveal anything unless it can release within a year of the reveal.
I don't quite like this strategy. Microsoft is getting tons of flack for their strategy now but that's because they already have a flaky reputation for delivering on promises of the past. But at least Xbox gamers have a multi-year roadmap they can point to for non-GaaS titles. Will any of them actually deliver in terms of being high quality or living up to expectations is another question, especially given it's Microsoft.
Yeah I did give Sony flack for stuff like Dreams which was revealed way too early, but otherwise they delivered on the vast majority of the titles they showed off earlier. UC4, Horizon, Days Gone (after patches), GOW, GoT, and 3P exclusives like FFVII Remake, SFV (after a couple of Seasons) etc. I don't get this new strategy where they are keeping so many of the non-GaaS titles in the dark.
