Was Hulk gonna turn Gray in Age of Ultron?

One of the interesting things that happens when you're a fan of a certain property is that you find different parties working on a movie or a TV text offering conflicting information.

In the case of Avengers: Age of Ultron, there is now a question of whether or not the Grey Hulk, an evil or perhaps angrier, less controlled version of the famous green giant was to appear.

The early trailers for the film, which depicted a battle between Hulk and Tony Stark in his Hulkbuster armor gave some people the impression that Hulk was looking grey or grey-ish, suggesting Grey Hulk would make his debut appearance.

As the film has shown, this is not the case. And, according to director Joss Whedon and producer Kevin Feige, was not the intent.

Entertainment Weekly: During the Hulkbuster fight, am I picking up on the Hulk turning gray when he gets especially irate? 

Joss Whedon: You’re not picking up on the Hulk turning gray in the sense of a Gray Hulk. What you’re picking up on is that we wanted to put a little spell on him. What we wanted to evoke was a sickly, out-of-control, diseased-brain Hulk. We deliberately took the green down and made him look unhealthy, but not in a gray-canon way. … That literally never came up. 

Kevin Feige: It came up with consumer products and marketing! I think there might even be a Gray Hulk section of a [toy line] somewhere, which we kept saying, ‘It’s gray-ish.’

Now, however, a report by WIRED on the effects of the film, says different.

According to them:

Initially, Hulk was actually planned to turn grey when he is angry Hulk in the Hulkbuster sequence, but hey, everybody wanted the green guy. So in the end, ILM just changed his eyes to make them look more sullen when he is under the control of Scarlet Witch.

At the very least, it suggests that the idea of him becoming canonically Gray for a bit did come up. So, it seems that there were conflicting views on whether Hulk becomes Gray or not.
