As the scheduled June 2015 release of Hello Games' highly awaited 'No Man's Sky' during the E3 2015 or Electronic Entertainment Expo nears, confusion and anticipation are reaching fever pitch as there were reports, Sean Murray's team will not be able to meet the deadline. E3 is the world's premier trade show for computer and video games, which will be held from June 16-18, 2015 at the Los Angeles Convention Center

A report by VC Post said that developers at Hello Games are working insane number of hours in a mad rush to create a revolutionary breakthrough in the gaming world. Indeed, the report said that No Man's Sky is expected to become the biggest title in the gaming community this year in terms of scale as it involves a massive 18 quintillion worlds, beyond what the human mind can imagine.

No Man's Sky features procedurally generated open universe that allows players to explore and upgrade their characters as well as their command ships and starships. These massive features of No Man's Sky have ignited concerns amongst industry players that Hello Games will not be able to meet its set deadline.

A separate report by Christian Times, however doubted No Man's Sky will be available in next month's E3. The report said Hello Games would not be one of the exhibitors in the Los Angeles event, casting a grey sky in No Man's Sky's release.

According to the report, the lack of additional details from Hello Games' executives has further fueled speculations that the developers need more time to complete the development of No Man's Sky. There were also concerns that the developers have encountered some issues in the development of the No Man's Sky. What everybody is certain that the 10-man team of Hello Games are pushing hard to deliver on their promise.

GameSpot journalist and host Danny O'Dwyer posted on his Twitter account that No Man' Sky PS4 relased would be further pushed until 2016, adding to the frenzy. However, others are hoping that Hello Games might pull a surprise and eventually release No Man's Sky without the fanfare.

Christian Times also cited a report by Cyberland which said that No Man's Sky would be released this August 2015 on the PlayStation 4 platform. However, the PC version will be available in 2016. Another report by Play Magazine echoed the same information that No Man's Sky will be indeed become available within the third quarter of this year.

In an interview with The New Yorker, Murray also expressed concern about the release date of No Man's Sky. "The biggest worry for me is that we release the game because of all the momentum behind it before we are happy with it," Murray said during the interview.

He went on to say to describe No Man's Sky, "We didn't want you to break your legs and get hurt. It is about exploring. We didn't want people feeling nervous") to its obvious appeal with consumers . I think that one of the reasons No Man's Sky resonates is that, at a very reductive level, it's bright -- it's colorful, vibrant."

No Man's Sky will be exclusively available on Sony' PlayStation 4 (PS4) platform. Meanwhile Microsoft stated that it has no regrets that "No Man's Sky" will be launched exclusively on PlayStation 4 platform and later on the Xbox One platform.

Hello Games was founded in the summer of 2008 by four friends, Sean Murray, Ryan Doyle, David Ream and Grant Duncan. "We'd worked together at developers like Criterion, Sumo Digital and Kuju Entertainment. We wanted to bring back fun to games. We saw them getting more and more serious and we missed the vibrancy of what we played when we were growing up. We talked about how Mario Kart had become nonsense when it had once been so amazingly competitive, and how bright and colorful had started to mean casual and easy. We wanted to bring back deep gameplay and great quality," Murray said on the web site of Hello Games.
