May 17 will tell about the future of the Arma series

Arma remains a popular environment among military simulators: but the last numbered part of the series came out almost nine years ago. It seems that the franchise will soon break the deadlock: Bohemia Interactive is going to announce something new. 

There are no details yet, but it all comes down to a few theses: 

• May 17 at 19:00 in Kiev on Twitch will be a stream called "The Future of Arma" 
• The official Twitter account of Arma 3 has changed its name to Arma Platform 
• An insider named Biosphere thinks the new Arma is aimed at PCs and Xboz. Prior to that, no Arma came out on consoles 

At the end of last year, Bohemia Interactive introduced its new engine - Enfusion. At the same time, the company said that "any potential new Arma will use Enfusiom." It turns out May 17 can present a fourth part on a fresh engine?
