Shinobi602, a well-known gaming industry insider, shared via Twitter that Fallout 4 will be revealed at Bethesda's E3 conference.
Speaking via Twitter, Shinobi602 had this to say on the matter:
Fallout 3 gameplay debut: E3 2008 Release: October 2008 Fallout 4 gameplay debut: E3 2015 Release: ??? Believe.— shinobi602 (@shinobi602) luty 10, 2015
Of course, this tweet could be mere speculation on the popular insider's part; however, this isn't the first time that he teased an unveiling of a high-profile game well ahead of the official announcement. What's more, last week Bethesda confirmed that it will host its first ever E3 conference this year. It stands to reason that the company has something significant to reveal to the gaming community as it is unlikely that it would organize a conference simply to talk about already announced titles.
The accuracy of Shinobi602's tweet will be verified during Bethesda's conference on June 14, 2015.
