Shadow Realms has been trademarked by EA. It’s unclear what, exactly, this is, but you’re welcome to have a guess below.
You’ll find the Shadow Realms trademark through the link, which pertains to, “Computer game software; Downloadable computer game software via a global computer network and wireless devices; Video game software.”
This could actually be anything, but some sort of E3 reveal might not be entirely out of the question.
There’s also the little matter of Visceral Games’ rumoured Battlefield 5 project.
What do you think?
