I don't see Salvador running a bandit gang myself. He's still pretty crazy but not in that way. In any case I don't think the characters will go the same route as the first crew... what with the Vault map and all. The original crew went their separate ways on Pandora thanks to the Hyperion invasion, if the crew breaks up again it will probably be because they're chasing down different Vaults or leads, no real time to form a gang or militia like Brick and Roland.
If there's a sequel with him in it, I can easily see Salvador being the ones who dies. I mean, his name means savior in Spanish and when he's reviving other characters he often says, "If anyone should almost die around here it should be me!" I can just imagine Sal doing something really crazy heroic and blowing up to save everyone else.

You can only do it once a save/quit cycle. You'll need at least two people, your reward is based off of the level of the character sacrificed and the level ranges are keyed to the host's game. So your best bet is jumping into level 50's game and sacrificing a level 50. Anyway you have to make your way to the Bloodshot's Altar to Marcus on the top of the damn, you know where you rescued Roland from WR-D3N(that special constructor whatever it's name).
Anyway there is an altar behind where it stood where there is a fire pit and a button on the right. Have the sacrifice jump in, hit the button and they'll be killed(slowly by fire at that, no instant death). When they've respawned at the nearby New-U/Travel Station you'll have several items pop up from the pit. I did it with friends in TVHM, I was a level 48 in a team of 39's-40's. They got level 35 keyed purple and blue items. So I'm pretty sure the quality is tied to the sacrifice's level(maybe even their cash amount but not sure).
