Yeah, I think IM3 really set him up to think beyond the armors, I'd like to see some really crazy armor set ups too, but satellite lasers, tons of crazy weaponry, explosives and targetting. Chemical compounds, sonic/illusion tech. Craziness....
It would have been funny, if the whole Iron Man 3 was just Tony's nightmare, like the Dallas dream season. So the Mandarin twist does not exist, and they don't taken out the reactor, etc. But there is no chance for this.
