Scenario 1: He sells all the exotics people want. The elitist come on and bitch and moan about how "They earned their exotics". The thousandth flame war since the start of Destiny begins. Scenario 2: He sells a bunch of crap that nobody wants (even the elitists) and everyone bitches and moans about how Xur is worthless and how he could have brought something better/useful. Basically it is like this every week and will be until Destiny ends.
