I find it hard to believe any leaks from anonymous people on 4Chan. Unlike examples such as shinobi or Vergeben, they have no track record and suffer no consequences for making stuff up.
I could anonymously post that this E3's Nintendo Direct will have a trailer for Marvel Ultimate Alliance 3 that focuses on the Fantastic Four and Doctor Doom, reveal that Animal Crossing has been delayed to 2020, reveal release dates for Bayonetta 3 and Link's Awakening, show off footage for Erdrick and Banjo in Smash, announce F-Zero: Omega Grand Prix (developed by Sumo Digital) and Kirby Air Ride 2, reveal a new IP that involves transforming robot cats, and show ports for Persona 5, Devil May Cry 2-5, Rare Replay, and the Master Chief Collection, but that doesn't make any of that seem true or likely.
