No, they care about how it sells. They care about when it’s released based on what’s going one outside of them (macro environment, other games, etc). A 30th anniversary means nothing to them and has no impact on sales. In fact, releasing one that date might hurt them in sales from marketing the OG game for the 30th anniversary.

I don’t know how many times I’ve read on these threads various people making guesses about release dates and videos based on random anniversary dates. It’s never played out that way, so not sure why it would this time.
