I'm pretty sure it's dependent on where you are, latitudinally speaking...

Check the view from my city:

It's clearly rotate about 90 degrees from the real-life shot in the video.
Not only that, but Luna isn't perfectly tidally locked with us, so it gradually rotates its face in relation to us, in contrast to the idea that it is always the same. Granted, takes hundreds of years to change a few degrees, but it happens.

And if that big Hive guy was on the rim of it and he started running really fast, like a clown walking on a barrel, it would probably spin a little.

I didn't even think of that....

I'm a little confused. Are you saying that the 135 degrees indicated on the image is incorrect? Because I just checked, 135 degrees seems accurate.

I actually didn't know that, thanks!

As seen in this GIF:

the Moon clearly librates (its axis of rotation oscillates) over the month.

So, adding up so far, the rotation observed in the vidoc could be attributed to:

• Libration
  
• Location of observation (along with time of day)
  
• Not-so-perfect tidal lock

However, also bound to the not-quite-tidally-locked, along with the fact that over time the Moon does show more of its far side, is the fact that it's getting farther away. So, to achieve a rotation of over 20 degrees (best-case scenario, if you take my other photo as reference), it would take a LOT of years, but the Moon wouldn't be as close to Earth as shown.

So, yeah, I'd attribute it to slight oversight. I hope they either 'fix' it or make it into an even more awesome story. :)

Yesterday night (about 11pm local, 21st October 2013), the Moon was almost in the exact same orientation as in the ViDoc over Rio de Janeiro.

Now that I thought of it AND played around in CAE software (killing a mosquito with a cannon, I know...) I'm sure it's simply a matter of time of day and the height of Moon in relation to the horizon.

Nice catch about the rotation of the moon! I hope it gets addressed in the game. Knowing Bungie it's quite possible they'll never actually explain why it's rotated and we'll just have to speculate.

A thought about the different placements of the hand cannons, what if it is based on the gear you have? Maybe different belts or whatever have differently placed holsters for your weapons.

I can definitely see Bungie not talking about it. They've even said that they don't want to fully explain everything, they'd rather we had our own perceptions of some things.

I like the idea of weapon placement being based on your gear, it makes sense and would be pretty cool :)

Gear-based makes a lot of sense. That's why I think weapon placement will be based on class; Bungie has said that the gear will be different between the different classes. (For a different look and feel)
