Does anyone know how this will translate in terms of difference in games?

For one, all new PS4 games from October onward will be REQUIRED to have PS4.5 version which has 1080p+ resolution requirement.
They will also be required to have the SAME or HIGHER frames-per-second as PS4.0 version...  So higher fps seems likely to be common.
Other than that, I expect expanded scope/usage of stuff like GPU-physics, GPU-audio-raytracing, better lighting and graphic FX.
Morpheus/PSVR games already are pushed to have high frame-rates, for which they will have to sacrifice normal graphic niceties,
so the PS4.5 version of those VR games will be able to add back graphic FX, and/or go for even higher FPS, etc...

In Eurogamer's take on the leak, they discuss how there will be feature-parity across 4.0/4.5, i.e. that gameplay is supposed to be the same...
But then describe it by saying that PS4.0 might allow for 2-way split-screen gameplay, but PS4.5 might allow for 4-way split screen gameplay.
...Which really is a significant difference in gameplay IMHO, but that sort of thing may be technically allowable, apparently.

Where do you get required from?

Sony really wants Neo support on all games from October onwards. While older titles can have Neo features patched in, the platform holder will not allow new titles to add Neo features at a later date.

They don't allow you to add it later from October onwards, but devs can still ignore it. The fps requirement is so that ps4.5k versions don't run worse due to using too high a resolution, which must be minimum 1080p. So higher fps is not likely to be common, it's simply required to be equal or more stable than ps4.

It all points mostly to a resolution bump for the Neo version, with likely downsampling to 1080p or upscaling to 4K. I doubt any devs will go for specific graphics or audio features for the NEO version, bump up shadow detail and reflections at most. No point in supporting a whole different enhanced lighting system.

Sinply look at the differences in XBox One and ps4 games, for ps4 and NEO it makes even less sense to add extra features. Resolution will be the biggest difference, next to a more stable frame rate. The question is will ps4 games now slip to 900p sub 30fps and XBox One versions to 720p? Or will things stay the same with NEO rendering at 1440p with better AA. (I guess the latter)
