I'm afraid to say it,but....if there fixing MCC now that means that there will be no classic gameplay in halo infinite. There fixing it so classic fans go to the past while the new halo goes forward.
When I say forward I mean mudslide down.
Halo MCC has forge ,later we get custom browser that's there way of saying "we don't want classic fans,sorry""
Or they might just, you know, be nice, and their work in MCC has nothing to do with their future plans. They already implemented the old art style, something classic fans have wanted, so there’s nothing stopping them from making the next step.
There are also still a couple of annoying glitches in Halo 5, so you could take that to mean, “We don’t care about modern fans, sorry.”
