Old PSVR games getting new patches... Ps5 Related?

In the last few weeks Resident Evil 7 and VR worlds both got a random update after being left alone for years. Today Everybody's Golf VR and The Playroom VR have had updates pushed.

Could this just be a massive coincidence, or are we looking at games being updated in time for the Ps5? Whether it's a compatability fix, or hopefully improved fidelity / fps?
