[2019] The whole MCC might come to PC faster than we may think

Just something that I've been thinking.

Halo's 1 through 4 runs on the same base engine, which was modified and improved game after game. You can see this for yourself in the latest post where they show parts of the source and comments from 1999.

What this means is that after porting one game, they probably will not have to start from scratch for the other ones, especially on the things they said they're working on such as the interfaces and control stuff.

This doesn't mean the games are all coming soon, they will probably come soon enough and won't take years as some are worried they will.

But that's just my theory, A Game development theory.
