1) Levine mentioned that the Vigors also work like EVE in Infinite, since looking at the Bucking Bronco, it looks like there's a ammo-type HUD for it. It also looks like there's as many Vigors as EVE syringes, since the new Demo shows another Murder Of Crows Vigor.

2) It's advertised, and a lot of the ad suggests it's affects would work like Hypnotize. They more likely have listed familiar Plasmids to be Vigors, but they're still coming up with alternate names to call them, since it would be too much of a Rapture connection to call them "Electrobolt" and "Incinerate!".

3) It's more likely guns and ammo, much like in the first demo when Booker grabbed the riffle out of the barrel.
