Although Sony has already confirmed that it won't be at this year's E3, it seems that, ahead of the big show in LA next month, some new information could be revealed about Naughty Dog's PS4-exclusive, The Last of Us: Part 2.
This has been suggested by well-known insider Akoji, who said on ResetEra that there will be an official announcement regarding the sequel to The Last of Us before E3 2019, but they didn't reveal anything else.
Could it simply be a new gameplay trailer, or perhaps something more substantial like a launch date? Time will tell.
