Cross post from the community thread:
The news about Locke is incredibly interesting, far more so than the news about Halo 5's MP so far. Halo 4's lore, while combined with the EU, was a good effort, most of the fanbase did not appreciate it because they had no idea what was going on due to the extended reading that was required to understand the campaign, which unfortunately was not self sufficient.
Now this is an even bigger risk on 343i part. People didn't like playing the Arbiter, and as a result the Arbiter missions in Halo 3 were removed for a Master Chief only game. The fanbase* wanted to play as the Chief in the numbered Halo games. In my opinion?
. The rechargeable and actually useful active camo ability the Arbiter got in Halo 2 is something I still miss in Halo to this day.
The Arbiter missions had their downsides but also had their brilliant moments. It was a huge bonus to Halo's lore and frankly we have not seen anything in the games since. Halo 3's campaign, especially when we were on Earth, couldn't even come close. It's telling that most of the story in that game is concentrated in the latter half, because it felt like the first half was to shut people up about the lack of Earth based MC missions in Halo 2.
Make no mistake, this can go really well or really badly. I don't see a middle ground. Locke could present an interesting twist with proper stealth tactics, which can be very fun if applied correctly. Stealthing through entire missions as the Arbiter in Halo 2 is something we have yet to see in any other Halo game thus far. And it is incredibly fun, especially on higher difficulties where the risks of being seen are increased tenfold. Of course, you could always shoot your way out and mix things up a little, but approaching a set piece encounter with multiple ways to defeat the enemies is something always appreciated. That's why the big sections in Halo 3 were fun to play in; you could take on the Scarabs in multiple ways. And from a gameplay perspective, this is where Halo 4 lacked. Lack of ingame set pieces or the ability to approach encounters in multiple and actually fun to use ways. No, using different weapons does not count.
So my take? Bring it on. Just do it right.

To add onto this, I think a three pronged Campaign would be even harder to do if they decided to investigate the Arbiter's POV as well. Same principal applies, however.
For example:
Locke- New Spartan Abilities, enhanced Mjolnir Mark VI Gen 2 or even Mark VII armor
Chief- Broken, old armor with just sprint.
Arbiter- Elite armor and camo.
This could lead to an interest contrast between the three characters and more variety. It would be even more radical to have the ability to switch characters, e.g. imagine in Halo 3 during the mission "The Storm" you could possess either the Arbiter or the Master Chief similar to another player taking over the Arbiter in coop.
One thing to take away though is that the game seems to be focused on the Chief. Even when you don't play the Chief, he is still the primary target. That's a plus, but it can still go wrong: Let's note that a somewhat similar situation arose with Cortana in Halo 3, although to a much greater extent. She was shoehorned for most of the Campaign and only appeared in those annoying Cortana moments. That's really what 343i need to avoid.
There are multiple ways to approach this:
->Make Halo 5 longer than 6 hours while remaining interesting at the same time.
->Give Locke less than 50% of the playtime. I doubt this will happen.
->Make the Chief missions exceptionally long and fun to play in. The danger of this is that one character may end up as stale in comparison to the other.
The more I think about this decision, the more worrying it becomes. This is going to be very hard to pull off.
