Earlier today saw Avengers 4 concept art leak online featuring the surviving Marvel heroes and a piece with the new look and weapon forThanos.

Now more possible Avengers 4 concept art leaks online, this time possibly of Vision in his invisible / spectral form.

Last we saw of the Vision, the Scarlet Witch had used her powers to destroy the Infinity Stone in order to stop Thanos from fully assembling the Infinity Gauntlet; however, Thanos used the Time Stone to go back in time and rip the Mind Stone from the Vision's head.

It was thought the Vision had died, but if this Avengers 4 concept art is legit, it's possible Vision may have become incorporeal and aids the Marvel heroes in some way.

Speaking of heroes returning, Chris Pratt recently touched upon Star-Lord in both Avengers 4 and Guardians of the Galaxy 3.

"I'm slated to film [Guardians of the Galaxy 3] in January so we don't know yet time-wise where that lines up," Pratt told MTV. "I'm hoping it's not the last you see me, but you can't be certain."

Jeff Goldblum was also asked about Grandmaster for Avengers 4.

"I don't know. Who knows," Goldblum said. "They've got a good imagination. Kevin Feige, Louis D'Esposito, and Victora Alonso over there, they know what they're doing. They make good movies. Well, see if I could contribute anything to what they were doing. I imagine this, that my brother, the Collector played by Benicio del Toro, maybe they see us together. I don't know. Who knows, but my character can do anything. I've got more super powers than all of them put together... I'm the Grandmaster. You can't kill me. I can do all sorts of things..."

The Avengers 4 has a May 3, 2019 release.
