I think the difference is that outlets like iOS, Android, Steam, etc. didn't have an established status quo. They emerged as independent alternatives. If run of the mill console gaming is Coca-Cola then an iPhone is Diet Coke or even just Pepsi. But taking something that's already established and running smoothly and suddenly replacing it with something else, that's New Coke.
To me, it seems like a sucker bet since at the risk of pissing people off and suffering whatever consequences that can come from people being pissed (which in the digital world usually means focused attempts at piracy), the benefit of cutting off used games is unlikely to be significant enough to overcome the financial woes that are likely the result of bloated budgets. I just can't see the revenue stream growing that much if the only meaningful change is the annihilation of the used market.
