Verreken

It would be stupid to remain on Arma 3. More than likely developers/owners will gain access to thing prior to the release of Arma 4 (if it ever comes out) allowing them to start the framework, building the servers, etc. 

Ideally the code will be some coding language used other than just for Arma (like SQF) so it will be a lot easier for developers to actually create things for the server. Ontop of that with how Arma reforger is you wouldn’t need to launch your games with the specific mods before joining the server, you can just download the mod as a part of joining the server. That  is a massive reason why Olympus has stayed unmodded (with exception of client mods), so many newer players launch arma with no mods and can easily join Olympus. If they tried to join Anzus they would have to find their mod list and download all their mods and relauch their game with all of them on. Then if they wanna swap to a different server they have to take it off. With Arma 4 that would more than likely never be an issue again.

Arma 4 would also bring TONS of players back to Arma/Olympus even if it is temporary, but would be wasteful not to capitalize on it.

There are already life servers on Arma reforger which uses a beta version of the enfusion engine and dayz uses and even earlier version of that as well. So the possibility of servers being put up fairly quickly is pretty high.

If olympus were to remain on Arma 3 only it would probably die off. The already low population on Arma 3 (not just olympus) would shrink even more with the newer game coming out.

Ye stay on arma 3, an already dying game before arma 4 is even out. good one 

Without saying too much, I can almost promise you we will make a relatively quick and well developed swap to A4

We need these

why not medics don't rev people any way. Useless retards add these and defibs
