They wouldn't tie it to GotG2.. that's way too cosmic for S.H.I.E.L.D.

As for Doctor Strange, I doubt it will tie in, since it seems to be a hidden battle that takes place away from the public's eye.

Graviton would be the perfect villain for Season Four.. You don't introduce a major Avengers villain then leave him to basically be an extended cameo. But if not Graviton, then definitely the Kree..

They need to bring back Blizzard and Deathlok and introduce Manifold and Phobos somehow. For Stonewall and Druid, I think Absorbing Man and Lash will work for both, respectively.

AIM, MODOK, Ten Rings, Mandarin, etc. should be saved for a possible Iron Man 4. They're way too big to appear exclusively on a TV series.
