Firstly I think its very unlikely that tmw will end in 2018. Sure, the developers are not working on it anymore, but they said multiple times that tmw will stay online as long as there are players playing it.
They are however working on a next version of tmw, based on hercules server. It currently has new content, maps and art and quests to keep you occupied for quite some hours. Also lately they (mostly crc member micksa) are redesigning the best of old tmw and adding it to the new server.
you can find the new server on testing.themanaworld.org.
