Just caught up with the last few pages (wanted to see The Winter Soldier first) and this is looking pretty cool so far. Tony and Stark Industries definitely look to be the catalyst for this one.
Jarvis' voice actor is listed in the cast as being given his own suit, Tony is apparently wearing his Mk 42 (albiet colour inverted) and Ultron is apparently some thing to do with his tinkering.
Also, after a bit of checking, Hawkeye is using the new Hoyt Dorado GameMaster. They must have a contract with Hoyt for the series, since he was using a heavily modified Buffalo last time.
But I don't see Coulson anywhere in the cast list, since they're already filming I assume something in AoS is going to have him missing this one out.
