Eh, I mean GoW Ragnarok did way better on PS5 than PS4 when it launched, despite PS5 only having a 22m installbase at the time.
The bigger audience for 1st party exclusives will be on the new system even if it's sales are much less. Cross-gen may last a bit longer but it will definitely get exclusives eventually.
Sony are not going to be releasing 1st party titles on PS5 in 2035.
