I have Reach installed on my Hard Drive. I’m buying CEA tonight. Can I use the CEA disc to launch the entire Reach multiplayer? Or do I only get to play those 7 maps and have to use the Reach disc for the full experience?
I had the exact same question man. no idea.
ya me too and odst too.
I too have the this very same question. I’m not totally sure how it works exactly but I hope someone can shed some light on it…

As far as I am aware, the CEA disk can only access the 7 remakes, and the Anniversary playlists. If you want to play the rest of Reach multiplayer, you’ll need the disk, as well as whatever DLC the playlists require. That’s what I understand anyway 
I just got the game (Walmart screwed up and shipped early), it comes with a code to download the Anniversary map pack.
However, the game does allow you to launch “Halo: Reach Anniversary Multiplayer” which launches a version of Reach with access to only the Anniversary maps and playlists.
