To me it all seems pretty clear to be honest.
Higher resolution games and it is up to the developer if they go for improved 1080p versions (though there will be 1080p modes). Many PS4 games run at 900p or have a blurry look due to all kinds of AA solutions and the Pro offers a solution to that. Just compare the iq of Uncharted 4 to a lot of other 1080p games, most on PS4 are less clear (Arkham Knight would be an example of that). Unfortunately, older games mostly don't get an update and run in a compatibility mode but nothing about that has been unclear to me to be honest, outside from people speculating it may have done otherwise.
Its main marketing point is for the coming of cheap(er) 4K TV's, which are getting more and more affordable and in some countries (like mine, the Netherlands) 4k streaming is already feasible, so I know many who jumped ship to a 4k television. The PS4pro complements that, on top of doing everything else the PS4 has to offer.
