If the Quantum Bands are related to the Quantum Realm, then perhaps there really is a possible connection here.
The Quantum Realm was a concept introduced to the MCU in Ant-Man that we expect will become more important in Ant-Man and the Wasp, as well as other future Marvel films.
It’s also the name of a powerful Marvel character who we have yet to see as part of the MCU.
Is James Gunn’s tweet really just a picture of a VCR or is it a hint of what might be coming in Guardians of the Galaxy 3.
