Not much today.
-Storm states that making ultra-HD texture pack makes no sense. The difference would only be noticeable from like one meter distance in hangar and only like 0,1 percent of players would download it anyway. In words of Storm: "It would be absolutely pointless to waste time on creating, testing, distribution and support of this pack.";
-WG is currently working on complete analysis and rework of WoWp, they want to fix it and revive it;
-Mines were tested in WoWs internally but with unsatisfactory results (RG: I would revise the whole camouflage system before trying anything else. Makes no sense that a ship can cloak at 500m on open sea and with no smoke deployed).
