So what can it mean?
First, Eternals shall be partly set in the past.
It could mean more scenes with Hank Pym, Janet and Bill in the past and maybe more Peggy Carter!
But the most important thing to me is that it can be seen (by an optimistic guy such as me!)as an indication of the modus operandi chosen to integrate the Fantastic Four into the MCU.
Let's go for the past, let's go for the 60's if you want, though I would prefer the Ff to be contemporaries of Hank, Janet and bill as a first generation.
What are your thoughts about it?
