He's wearing the newfangled 343 Mjolnir in all scenes we've seen so far on the FUD. He's definitely got the new helmet on when Cortana wakes him up, there was a cutscene in the latest wave that showed it...
You misunderstood my post. I was trying to point out that, if people have such a problem with the fictional explanation given for Chief's armor change, and if one were putting effort into a good fictional reason for the change, then from what we know of the story, this situation could work: Have the Chief start off with the Mark VI at the beginning of the game, then when Infinity crashes on the planet, have the Chief upgrade to the armor we see he has now.
As for me, I don't really care about the fictional reasons for the armor change. I don't think it matters for some relatively small detail like that. What bothers me more is that I think it looks worse than what we had previously. I feel the same way about other small details. For example:
Yes... I reckon they didn't do this to avoid needing two Chief models.
A shame, i would have loved to see updated Halo 3 Mark VI and then this new armor. And there is no logical way for Cortana to have upgraded the Chiefs armor really. Firmware for sure but not anything else.
Of course the ship now carries MA5Ds and BR85s... Why weren't those used in Halo 3? Especially the new BR, which seems to be post-2553 weapon. So there's something odd going on. Maybe. Especially if Cortana is rampant too.
Whatever fictional reasons you could want to explain these circumstances, I don't feel like they matter. Those guns weren't used before because they didn't exist, and they didn't exist because the developer had a different goal in mind for the sandbox. This is a game, and gameplay should come first.
Now, if we're talking about major event retcons, like what Reach did, then that's a whole different discussion. Though my problem with Reach's changes come more from the fact that a) I think we got a weaker narrative overall compared to Nylund's work and b) I don't see why Bungie couldn't have delivered a game within the timeframe Nylund wrote out. I'd have less of a problem with Reach's fiction changes if the story delivered was strong enough to stand on its own.
