By the time Avengers 3 comes around, there won't just be one or two new members on the titular team - there will be several. Ant-Man, Doctor Strange, and Black Panther will all have had solo movies by the time this movie comes around, and they will all join the team, while Ms. Marvel could make her first on-screen appearance and Mockingbird might go from Agents of S.H.I.E.L.D. character to movie character as part of the new-look Avengers. Supporting characters Wasp and Falcon may have joined the team too. Of course, in some of those cases, it might not happen, but the fact that they are all at least rumoured is very exciting indeed.
