I feel IM has always being pretty high up on the list, he has being and original Avenger since the 60's.
Sure he doesn't have 20 different comics on the go like Spidey and Wolverine and thats a good thing, more of there stuff suck (and Spidey is my top character) but overuse of a character isn't always a good thing.
Also I would love RDJ to stick around for more, but lets be honest he isn't getting any younger, so they would have to film a few back-to-back to get him while they can, cgi can work to de-age IF done well, but I'd rather they don't go down that road.
After RDJ is gone, give Iron Man a rest while they bring in new people, then carry it on, not reboot just recast.
