PlayStation sees PC releases as opportunities for growth, not cannabilization
Basically it means the PC ports don't cannibalise console sales, so they will continue them
Cannibalisation is this sense means Day and Date.
Not happening.

Regarding DAY & DATE PC
FROM Live stream Q/A
Q: Do you consider the cannibalizing of console if you focus more on PC?
(Hideaki) A:
We can use PC as a way to grow our network numbers (refrences Ghost of Tushima Legends) & rather than looking at it as cannibalism, the customers might look into buying a PS5.
(Herman) A:
Our strategy remains to launch Live Service games simultaneously on PC & PS5, otherwise know as Day & Date.
for our Tentpole narrative driven single player games they will only launch on PS5. This might also lead to PC players buying the console to play a sequel of a game they had played on PC.
