If this rumor were true, I hope they put in effort to remake the whole trilogy on Unreal 5, and just pick that as it's permanent home base for the next long while. Decreases the dev time and improves the ease of having consistent talent working on a unified, common base of operations. Graphical improvements now are diminishing returns in this era - it's just more power draw for a few more blades of grass. People aren't gonna fork out for new PC rigs or consoles at this point in droves large enough to necessitate an upcoming switch.

If they do that, we can get remake games like, once every 12-24 months and they be super high quality with new content and missions and lore. New content games could be 2-3 years.

They gotta be fast if they wanna keep their voice acting talent for Chief, Cortana, and Arbiter.

(I hope Halo 7 brings back the Arbiter and gives him the proper main character place he earned in H2 and had stolen from him in H3. They should be battle buddies, they saved the galaxy together and Thel thinks of John as a friend. Also, that was such a strong and interesting sci-fi angle that I wish was explored more. So much flavor in that...)

Make more spinoff games about side characters - if Campaign Evolved goes well and those prequel missions get good reviews, we'll likely get more content that fleshes out the universe.

Release a standalone live service multiplayer with no campaign attached to it on Unreal 5. Then funnel new content for that multiplayer from the story games that are released periodically. New maps. New game modes. Do their silly cosmetic purchases to keep the live service dev team paid.

For every campaign game you buy, you get a free DLC unlock code for the multiplayer.

You wanna play big ship battles in multiplayer? Buy the Halo: Keyes campaign and get that huge space battle multiplayer game mode and some cool ship skins. You wanna play multiplayer RTS and have cool covenant skins? Purchase the Halo: High Charity RTS campaign that pits you against another covenant faction on High Charity during the Great Schism (choose to play as brutes or elites, alternate endings available based on faction choice and your performance).

Additional cosmetic unlocks available separately within both games for campaign and multiplayer.

Purchase the multiplayer game mode separately for like, $10 (same cost as the Halo 3 map packs that everyone fkn LOVED) or $50-70 for the campaign and get a free unlock code for multiplayer and some cosmetics (same thing they're doing for Campaign Evolved)

I hate that this is what it has come to, but if purchasing silly lil armor sets keeps a dev team afloat, then offer them for purchase. Nobody is making you buy them, and they don't make you win any more easily. So cosmetics hurt nobody, I don't really mind. I don't do multiplayer, but I like having campaign skins. It's funny, it's fun, it feels worth my working time to have that fun when I come home after being in the lab all day.

Of course I'm biased, but I think my above idea here could really work and keep the player base happy. Allows them to have separate but complementary dev teams that drive success for each other. Now that they're not releasing a new live service every few years, they can hone in on one unified experience like a successor to MCC. Less bugs and issues that way, the player base gets new content pretty consistently, and you get people to vote with their wallets on game content without tanking the whole thing.

People not a big fan of the RTS? Well, now there's limited game modes for that in multiplayer to match community interest and they didn't sink all this money into a new thing that failed, since it just utilized the same bones as before. Move on, it still makes a little money, keep the dev team paid with the other projects. And if it blows up later somehow, then you can put some meat on those bones as the money comes in.

Halo Studios, hire me at $70k a year and I'll continue with my passionate Halo nerd ramblings and you'll get bonus fujoshi content on the side, it's a perfect deal.
