...carrying different wares on different days than he is available now. It would fix some of the "go get item X from Xur" quest problems where you have to wait for him to show up for days.

The first time I got that quest, it was a freaking Sunday. I threw a fit. I was like "Could I just kill a ton of guys intead?"

I could definitely see a new vendor that acts like Xur. My problem with Cody's idea is that there are currently too many currency options as is. I'd hate having to carry around yet another random drop to upgrade a weapon/armor

It's not my idea. I would hate to see that happen. But that's my guess as to what WILL happen.

If we really are getting a new social space perhaps we will also get a new Agent(s) of the Nine? The Queen and her brother seem to know a lot more about them than the Guardians do...

I was thinking along these lines, too. A new social space, and a new fancy upgrade vendor.

Hopefully these will just reset the last 3 damage slots and the last couple of armor upgrades for both Raid and Exotic weapons.

Bungie adds two new items to the loot pool of the raids, the vex thingamabob, and the hive thingamajigger.

These items work like the crux, in that they drop from their respective bosses. Unknown if there will be harder versions of the raids in order to get these drops, or if they will just drop in the current ones.

To upgrade a raid weapon, you use the appropriate item plus some materials or whatever. Bam. 365 version.
