I wonder how they will make Arno Iron Man 2020 a sufficiently different read to Superior Iron Man.
Inverted Iron Man was about corporate evil amped by mad science. That version of Stark was basically a lazy hedonist with petty goals: turn plastic surgery into an app that needed routine payments, then sit back and collect the money. Spend money on orgies and booze. He had no grand goals, and pretty much spent just enough time in the laboratory to keep the money flowing.
I suspect that Arno will be about aggressively fixing everything everywhere with mad science. I think he will be waayyyy more ambitious than Inverted Iron Man ever was.
