Among all the Bleeding Cool rumors, the Inhumans one seems more plausible to me. Feige may be a fan of the property but the early head start by AoS is going to limit the studio creatively, and we all know Feige wants to stay in the driver's seat for the MCU. Among all of Marvel TV's efforts, AoS seems to be the biggest thorn in Marvel Studios' back, and it wouldn't be the first time the studio did something that totally derailed the direction of AoS (bringing down SHIELD in TWS). I can see Inhumans getting pushed later and allowing them some time to figure out the Phase 4 slate and how Inhumans fits into that, and also how much they'll be willing to retcon because of AoS.
