Justice League: Superman Returning In New Trailer?

As you will no doubt have noticed, Superman was nowhere to be seen in the first Justice League trailer and the early footage released way back, but it looks like his return from the dead might not be preserved until the film is released.

According to a leak collated by DCEU Leaks (reportedly via a source with a positive track record), the next Justice League trailer will feature a huge moment for the Man of Steel. Here's their description:

"After the JL title card, we get the money shot. Batman is driving towards some kind of ship when Superman in the black suit, beard & mullet lands right in front of it, red eyes and an evil smirk (fire in the background, raining ash, great visual shot) while Batman has a look of ''Oh s***'' as the trailer ends''.

It sounds good, but it also sounds a little far-fetched. Are we really going to see Superman and Batman throwing down again? Would Warner Bros unnecessarily spoil such a big moment when we all already know Supes is coming back? Okay, so maybe that last one's a bit of a trick question after the whole Doomsday reveal, but isn't this all a little... silly?

The rest of the description sounds similarly weird. Spelling and grammar errors are the source's own:

''The trailer starts with the same footage of Batman recruiting flash, then logos(including the new DC logo). we cut to a montage of the team. Bruce talking to Diana at some kind of museum. Cyborg looking depressed as he walks through the hall of a high school (apparently we see him use some kind of holographic projection to blend in) with voice over from Victor saying ''I never asked for this. I didn't want to be some thing'.
We then see Aquaman in atlantis (apparently resembles castle ruins), talking with Vulko (William Dafoe) about his destiny. We see a motherbox being guarded by Atlantian soldiers when out of nowhere there's an attack. Steppenwolf takes the motherbox, Aquaman swims after him, Steppenwolf throws his axe at Aquaman & in slow motion Arthur dodges it.
We cut to Batman, WW, Flash & Cyborg being overwhelmed by parademons in some kind of tunnel, the tunnel floods, and Aquaman shows up to save the team. We get the ''dressed like a bat, I dig it'' then Aquaman asks Batman for help. We cut to the team entering the Batcave as Flash geeks out. voice over from Batman about the parademons(referred to them as creatures) kidnapping scientists. WW asks what's the plan as Flash asks Alfred for some service, Alfred walks off.
Montage of action(slow mo shot of WW falling while trying to reach her sword as flash tips it with his finger so she can grab it, Cyborg punches Aquaman as Aquaman throws him against the wall as the shot transitions into Aquaman throwing Bruce against the wall, Aquaman ww & flash guarding what appears to be the scout ship, Batman gliding into a parademon, Steppenwolf stepping on WW's chest, Cyborg standing on a football field). Flash then makes a joke about Cyborg looking like the tin man"

The problem is, a lot of it sounds very believable too, which makes this all quite worrying. But then again, the most believable stuff isn't new or it's based on pre-existing theories (in other words, it's not exactly revelatory), so who is to say this isn't just entirely plucked out of fresh air?

Either way, it's guaranteed to have a huge impact with fans if this is how it goes down: and if Warner Bros' only agenda is to get people talking about the movie, then it will do the business.
