I think it somewhat depends on how Switch does, and how much of a lead Sony has over Xbox in the USA and UK when the generation ends.
Sony's dominance of the console market is a lot less universal than it was with PS2. Xbox is still right on PS4's heels in the USA and UK, so they can't afford to take those markets for granted. Wii U did well enough in Japan, and Switch might prove very popular there, so I don't think they can take Japan for granted.
So the three biggest single gaming markets in the world are all fairly competitive. PS3's awful first couple of years, and alienation of a significant user base still casts a shadow over Sony. Does Sony recognise that they still need to be seen to be trying to do right by the consumer? So far it seems they do recognise this. So maybe their memory will be long enough to not repeat the mistakes of the PS3.
2 things I don't think Sony will do for a long time is: go with non-standard system hardware that is difficult to programme for; and introduce a new and very expensive bit of media technology. The former, because system hardware that is PC-like is just so damned easy and cheap to use. The latter, because we are moving to a digital distribution world, so it's unlikely any company is going to put a heavy bet on the success of another form of physical media which Sony would feel the need to either incorporate into a new system as an early adopter, or counteract to prevent a competitor from becoming the dominant player.
