Will there be updated versions/new maps?

I know the game is still very early in Alpha(yet still great) but I am curious what the plan on maps will be?
Will the community be able to make custom maps or is the plan to expand the current map in a warz type fashion?

Thanks for all info ^^

I know I heard that garry was working on a new map, havent heard anything in a while though

Bump. any more info?

Yes, they are working on a new, bigger map.
