I don't think everyone understands why we restarted the first map, so context for that one may assist to why there will not be any map resets soon. First that map was really really big, there was one town annoyingly enough in the 8000 range. This is why we have border control, that just got resized to 3000. The problem was that it was getting nearly impossible to find new chunks that had things like lapis, or heck even birch and pine trees. Around that time I think we may have known about villages coming up, but we did know there would be a replacement of biomes.
Currently our map can't find only a few things, emerald ore (which is tough enough to get since it only appears in 2 biomes, and is easy enough to get emeralds as it is), and the jungle and sand temples, which we have proven with the enderdragon is that one person will just go in and claim the prize anyways. I do not see it as a huge loss.
I'd say if you're bored, just explore a bit and see some of the rail lines, and what towns lie beyond them, you might be surprised at what you find, our server still has a ton of secrets and still tons of space for new things.
