Improved media depends quite a lot not on Jitspoe's development, but others. (models, textures, maps, etc.)
Maps- well, yeah, its up to the map makers to make nicer looking and nicer playing maps. A bunch of interesting maps have come out recently, yet we've never seen/played them. OTB is the only one that uploads them, the American side barely see's the new maps. And in matches, most clans choose the stupid basic Airtime1 or something else that looks stupid and basic. Maps are the map-makers and clans problems, not Jitspoe to make.
Textures- Textures can be worked on by community, also. The used to be a large topic making a community texture project by Yootz (19 pages of textures). It depended on other people making nice textures that we would then be able to use in maps. I currently use quite a bit of the hr4 textures from that thread, as most textures were made by people really wanting to make the game look interesting.
Models- Things that can be worked on by community too. Although this would be harder, and Jitspoe could work on and update the models that are checked for hacking. But community is able to create models, and submit them to Jitspoe who could tweak them and implement them in the game.
But maybe a design team / media sub-forum. I'd be willing to make textures and edit them, I've just only worked on tweaking some slightly as of yet to keep them in check. I don't want people to cry foul if I started changing textures, and they see something different than the norm. That's the problem with these things.
