Not long now until perhaps we get a little more information possibly. 
Another write up revisiting old news from an earlier post by Singular Gleam. This time from GamesIndustry.biz magazine:

The organisers of Develop:Brighton have revealed who will deliver the opening keynote for this year’s conference.
Sean Murray, founder of No Man’s Sky developer Hello Games, will take to the stage on Tuesday, July 9 in a fireside chat entitled ‘To Infinity and Beyond.’
The session will be hosted by Edge editor Nathan Brown and will cover the making of No Man’s Sky, its launch and the ongoing development that followed it, as well as how this has transformed the game. Murray will also touch on future plans for the studio.
He has also been named the recipient of the first ever Develop Star Award, the biggest prize of the inaugural event that recognises outstanding achievement and contribution to the industry.
Murray will collect this accolade during the ceremony on the night of Wednesday, July 10.
