But the experience working with the videogames will teach a lot of things, something like a hardcore playtesting for possible modules. Should I to buy a expensive magic wand, gunpowder & firearms, or to hire a squire to reload my crossbows from behind a tower shield? can I send my familiar to leave a paper with a magic teletransportation rune to go to a far zone, avoiding a hard climbing or rooms with traps? With informatic simulations they are going to test the rules about mass battles, ship fights, sieges against strongholds or skirmishes against warbands.
D20 system is nice for fantasy but it isn't ready for crossovers with different genres, for example planetary romance, postapocalypse or space opera, because the XPs reward should be different if modern technology allow a enemy to be too easier or harder to be defeated.
Let's imagine they want to publish a videogame about investigation and paranormal horror, like "the sinking city", with puzzles. The game studio may notice they need some changes and even to create a new d20 system killing some sacred cows as the six abilities scores. (Sometimes in the past I have suggested new abilities scores, courage(bravery), acuity (perception + astuteness) and spirit (karma/fate/luck/guardian angel, faith, hope and resistance against supernatural influences).
If it works, why to change it? Now players want the return or update of their favorite titles, and later new things will start to be published. And the cadence of books is slower, most of these are modules or bluff/lore/background than crunch(spells, feats, magic item, subclasses, races).
Before the next edition a new original setting will have to be published. When I say original I mean a new IP starting from zero, not the adaptation of other known franchise (like a videogame or movie saga). In the last years of an edition they dare to risk and to publish new ideas for classes with some special mechanic (incarnum, martial maneuvers, truename, vestige pacts, shadow mysteries).
And if the projects for the mass media (movies, videogames and teleseries in streaming services) are enough successful then a new edition would be too risky, not yet until there are too many complains about broken balance of power.
