preview for Marvel Avengers Endgame - special clip (Marvel Studios)

Given the radio silence from anyone involved in actually making Avengers: Endgame - the odd crumb dropped by Samuel L Jackson aside - some of the best recent pointers we've had on where Endgame's likely to lead have come from the trickle of images of new toys leaked on Instagram.

Look at that. It's not that clear exactly how building an enormous metal man is going to help sort everything out, but it's for Tony Stark's mate War Machine and includes two minifigures of War Machine and Ant Man wearing new suits:

Those suits definitely look like they match up with the new Captain America and War Machine suits teased by these action figures which surfaced in Vietnam this week, and will add fuel to the fire of fans who reckon the surviving gang will have to launch themselves into the quantum realm to retrieve their sadly disintegrated mates.

So, working theory: Stark doesn't die in space, builds this enormous robot to take War Machine and Ant Man through the quantum realm and they cobble together a plan from there.
