5. Hulkbuster Breakout
This toy is particularly interesting. The title indicates that it will be the Hulkbuster breaking out of Stark Tower, something which is entirely possible if Ultron takes control of the suit and makes the Hulk think that his friend has turned on him (that wouldn't make a lot of sense if he is being controlled by Scarlet Witch, but it's still a solid enough theory). However, what if this is in fact a containment unit for the Green Goliath after he loses control? A LEGO set earlier in this feature showed the Hulk in some sort of device which appeared to be trapping him, so it could be that Iron Man traps him in there in order to stop his rampage. Bruce Banner then being imprisoned in Avengers Tower wouldn't be too hard to believe either, as it happened in the Ultimate line of comics, a series which Joss Whedon has been in part inspired by. It also takes him off the board for Captain America: Civil War.
