Two major differences:
1. Kevin Feige isn't Chris Nolan. Nor JJ Abrams, nor M. Night. Those guys make a cottage industry of subterfuge; Marvel Studios doesn't.
2. Robin and Talia al-Ghul were major plot points; they obviously had a duty to keep it secret. And when fanboys guessed the truth very early on, there was no other option but (im)plausible denial. Someone like Wasp would NOT be a major plot point in the IM3 movie --- there's simply no room for her story (or any other Avenger's, for that matter) to suddenly blossom into a full-blown subplot that takes away from the main plot points featuring Tony, Rhodey, Pepper, Mandarin and Killian. Ergo, no need to hide behind lies and denial about a cameo character.
