The report states that about 30% of console owners have not used a PlayStation 4 before. These could be older PlayStation fans who previously played on PS1, PS2, or PS3, or Xbox and Nintendo fans.
Ampere Analysis analyst Piers Harding-Rolls concluded on Twitter:
“Sony claims that nearly 30% of current PS5 users have never used a PS4. Our consumer research shows that PS5 owners are more likely to be single-console owners compared to competitors. Given product availability since launch and where we are in the lifecycle, 30% seems like a pretty high result.”
