This is an article that references another article that appears to speculate based off what Microsoft has been doing recently. Besides the headlines, there really isn't much to go off of.
I can't find that reference in the article, but I may not have access if it's behind a paywall. From what I can see, Warren's article doesn't talk about it directly. But really, Combat Evolved is really old. I doubt they're going to try to remaster a game that already has a remaster. Truthfully I find it hard to believe that they've even kept CE relevant through the Master Chief collection. Most old games just aren't worth supporting, especially not ones with online multiplayer and such. I have my doubts that Combat Evolved will get a new release.
But let's say they DO make one, and decide to release it on playStation like this article speculates. This paragraph would accurately describe my thoughts on the matter:
Halo is the reason people buy xBox's. It's the reason I bought one. There's no sense in doing that, so I also doubt this will happen. If anything, releasing Halo games on other console incentivizes people to buy those other consoles. Halo was ported to Windows Vista in 2007 to incentivizes people to update Windows, for example.
Even if it's a remaster of the game only released on xBox. Why remaster CE? The community has stressed time and time again that they want to Halo 3 remastered, another ODST game, more Infinite campaign, so there's no incentive to come back to a 20 year old game. Halo from 20 years ago isn't a good selling point, especially when there's so much that can be done with modern halo that would be much more relevant.
I love halo CE because it's preserved. When I play that old campaign, I use OG graphics and OG sounds. I don't use the remaster because that's not how the game was designed. Halo is the way it is because it's from a different time period. Levels and areas are constantly reused to save space. If you changed this because you have access to new hardware, you fundamentally change the story of CE. If you keep it the same, you keep the limitations of 20 years ago in a modern game. It really doesn't make sense to me to remaster the game. I hope they don't remake it.
TL;DR
I don't think they're remastering it because it just wouldn't make sense to do so. I hope they don't remaster it again.
