I'm happy to read some news about the sound design.

Not only news, but good news :)
(thanks DeeJ for answering my question, too)

Bicycles with bells confirmed.

Dreams, realized.

The ambient sounds of Venus.

Venus is supposed to have "lush jungles" in this universe, right? I suppose it probably sounds something like a jungle.

Definitely Marty, Mike, and Paul’s music. Aside from that, the placeholder audio we had of someone deadpanning “Throw Grenade” whenever you threw a grenade was pretty amusing.

Grenades confirmed.

Rocket fly-by: the sound of survival.

Rockets confirmed.

If you kill a Vex unit correctly, they can make an amazingly satisfying noise. I could shoot them all day long for that noise.

Is there an incorrect way to kill a Vex unit?

Reloading.

Reloading confirmed.

For a while there were random surfaces you could hit that should have gone CRUNCH but went DING! like a bicycle bell instead. I was very fond of that.

Some interesting answers. One answer did confirm that there are rockets (the shootable kind).

Confirmed: Rocket Race returns.

I also thought the comment about the servers being indifferent to console types was interesting. Could we see cross platform play?

Maybe, but I don't think that's what he was referring to. He was just talking about the fact that from the perspective of Bungie's servers, talking to XBoxes isn't much different from talking to Playstations, due to the way the game's built. Meaning they're all using the same API/protocols or whatever. Which is sensible.
