Okay, I have the answers that this thread was searching for 9 pages ago!
It has been disappointing to have experienced such a lack of cohesive information from the Xbox Support team As Von Whovian said above, this whole experience has felt like a complete Charlie Foxtrot, and someone at Microsoft or 343i dropped the ball with communicating clearly to everyone involved what was happening. I have personally chatted with Xbox Support 4 times about this issue, and Microsoft Support about it once. I was given two different answers, and the funniest thing was when Xbox Support sent me to Microsoft Support for the answer, and they had no idea and sent me back to Xbox Support. Finally, after many conversations, excited moments, disappointments and probably 5-6 cumulative hours on my part ACTIVELY trying to get this thread's question's answered, it is over and I can breathe a sigh of relief.
Please keep in mind that I am from Canada, so your experience may vary by region. I preordered, and have now received, the Halo 5: Guardians Special Edition Console.
At roughly 10am local time I picked up my console from the store I'd preordered it at. I raced back to my computer and began opening the package and reviewing the contents. At 10:30 I took the plunge and opened the chat with Xbox Support. I resolved the conversation at 11:25 local time and here is what this particular support agent confirmed for me.
-The Console Digital Download Code WAS/IS eligible for the swap.
-The Limited Edition disc (with limited edition disc art) will be the version shipped.
-The disc will be transported in a Standard Edition game case.
-A download code for the Warzone REQ bundle and the Halo: The Fall of Reach animated series will be included in this package.
-I should receive the package 3-5 business days from TODAY (here's hoping!)
-I can view the status of my order here: https://myservice.xbox.com
For those of you curious about what the process looked like, here is the rundown of what was required of me, though I know that it was different for Von Whovian, so it may be different for you.
-Opened up a chat window with Xbox Support
-Waited while the support guy reviewed the article I sent him the link for: http://support.xbox.com/en-CA/xbox-one/games/halo-5-guardians-disc-swap
-Gave him my Gamertag
-Gave him my digital download code
-Took a photograph of the receipt/proof of purchase, the front of the mini download code booklet, and the back of the mini download code booklet that contains the actual code and emailed it to him. Put the receipt on the Xbox packaging box for effect. (The front of the mini download code booklet has a pic of the Chief and Locke, and a description of the downloaded content. The interior of the booklet is an ad for the Silver and Green Xbox One Controllers, and the Silver and Green Astro Headset, and the back contains the legal jargon and the download code)
-Gave him my Xbox One Serial Number
-Gave him my full name and shipping address
-Confirmed the Disc Swap
-Breathed a Sigh of Relief, saved the transcript of the chat, thanked the support guy for his good work and closed the chat.
-Elapsed time of chat (including a few extra questions from me): 55 minutes.
