It's as of now been proposed that the postponement in the trailer's discharge was to keep away from spoilers from Thor: Ragnarok, which has had a considerable measure of progress since its discharge half a month prior.
Cautioning: one of those spoilers lies ahead.
The individuals who have seen the most recent MCU trick will realize that Thor loses his correct eye towards the finish of the film, and closures it wearing an Odin-style fix over the attachment.
Beyond any doubt enough, that same spoiler was unobtrusively covered up in the Infinity War blurb.
In the event that you take a gander at Thor in the upper left corner, he is moved in the opposite direction of the camera, with the end goal that his correct eye is totally blocked from see.
Was this a think move to abstain from ruining the way that one of his eyes would be lost before Infinity War begins? It positively appears the case.
With respect to whether some other key subtle elements are covered up in the picture? Basically, we just won't know until the point when we can think back on it with knowledge of the past.
Actually, there's not a considerable measure else we can gather truly until the point that we at last have the trailer, at whatever point that may come.
