The die-hard Vault fans have been weather eye open for real signs to Fallout 4 release as a sequel to Bethesda Softworks addictive open-world monster game.

The Fallout franchise is undeniably one of the biggest RPG series in the history of gaming.The enormous success from the last main title, Fallout 3, touted as the best games of all time with its uniquely exceptional story, post-apocalyptic landscape and powerfully admirable shooter mechanics demands a follow-up.

The big question is, will Fallout 4 ever roll out? To answer this dilemma, we gather some news to back up the claim that this fourth installment could just be in the pipeline.

Back in November last year, Bethesda has filed a trademark for Fallout 3 covering all other media properties beyond the game itself. The Fallout 4 trademark is applicable to the product and digital media among others hinting that Bethesda might be preparing for a big launch? 

Bethesda's VP Pete Hines took to Twitter to confirm this news of trademark renewal.  

@G27Status not a hoax. our filing. just protecting our trademark . also helps  in dealing with infringement stuff

An IGN video was also published to to announce this move of Bethesda's Trademark renewal. Click this link.

It wasn't before long when Bethesda Softworks has also confirmed that its dev teams were on the works on the studio's next epic title.

"Parts of our team have also been in pre-production on our next major project, and that game is at the point where it requires the studio's full attention to make it our biggest and best work yet," said Bethesda in a statement at that time.

Trusted Reviews notes that 'The Elder Scrolls V: Skyrim' is relatively new to merit a sequel just yet, although, fans, would just love to have one. Elder Scrolls Online for Xbox One, PS4, on the other hand will just be a week old after its release this June.

Fallout 4 becomes the suspected series to target with the E3 2015 event other than the fact that a trademark renewal as well as Bethesda dropping hints of its next big title in the works adds up to the equation.  

Bethesda is releasing a plenty of tickets to the public who will be interested to witness the event unfold and hear any announcement of Fallout 4 release live. Fans can also opt to watch it all happen via live stream through Twitch.
