More advertising: Duh ofc

User generated content: Games are becoming more closed, new competitve games like Valorant have absolutely no user content despite the genre being built off it (CS1.6, etc)

Co-op play: Even franchises that have had long-running co-op features are removing them as publishers put more pressure on graphics

Diversity: Maybe more likely but I'm still sceptical

Cloud gaming: Not until internet gets significantly better worldwide, current could gaming platforms have universally bitten the dust

Early access: Not so much as for AAA games, unless you mean pre-order exclusive "betas" that are just an excuse for why the game is still broken
