I haven't read thruogh all posts since it's about bedtime over here, and it's time for a last post before leaving;
I'd second the map argument...
we could use more for each gamemode, and we'll even need more for future gamemode(s)...
of course we (the mappers) will continue to produce official maps, but keep in mind that we can only do them one by one, and that we are trying to meet certain standards regarding look, gameplay and performance, in fact it takes a while to make a new map...
I can only speak for myself, but I have concepts for four different maps lying around next to my PC which I would like to try, but atm I need to focus my attention on the one that's supposed to go out with 0.5.0.
And I think about the same goes for the other mappers on the team.
As Defender said, the automapdownload will be fixed with 0.5.0, so aside from waiting for us to finish new maps, it's up to you to get your ideas ingame!

in that regard, have fun...
... and good night! ^^
