"At the minute, I actually prefer my PS4"

How?

Like that is a genuine question, because damn near every facet of the PS5 is an objective improvement over the PS4, barring the DualSense which is a subjective answer as to whether its preferred over the DS4.

And every generation still has growing pains where-in previous gens are supported. This was the case between PS1->PS2, PS2->PS3 and so on. This generation leap gets the added benefit of not having hard separations between accessibility as almost every PS4 game (like 99% of em) can be played on the PS5. The same for the XBox, XBOne and XSX have cross gen support. That cross-gen availability is bound to prolong how supported the previous gen is.

Additionally, slowly games have begun to roll out to be PS5 only announcements so far. Final Fantasy XVI and VIIRebirth, Silent Hill 2 Remake, Stellar Blade, more than likely Spiderman 2 and Wolverine, etc.

The reality is that the jump between the PS4 and PS5 is like upgrading your GPU (in the PC space)... sure, it can play games with a better fidelity, but that doesn't mean your old GPU couldn't run them, just that the new GPU runs them better.
