From various sources, it looks like the new S.H.I.E.L.D. television series will have it's pilot episode air this fall. Even though it does not appear to have any of the major characters from the previous Marvel movies aside from Agent Phil Coulson (how does that work considering what happened to his character in the avengers movie?), the show looks promising. Coming from the writer/director of the Avengers movie, it should be action packed. And assuming this pilot turns into a full season, this could be the first step towards a variety of new marvel live action series.
