Well the final chapter came out today: http://www.mangapanda.com/katekyo-hitman-reborn/409
I have to say after years of reading Reborn am really going to miss it. Truthfully I really though Reborn would go on for another year or so but to no avail. Reborn had its ups and downs but it was always fun to read. Whenever Akira Amano decides to do for her serialization, I hope it is as good as Reborn was. Goodbye Reborn.
