I just tested the manual upgrade to 2.1.4 on my Kobo Touch to trial the new Calibre ability to create/manage shelves, and I was quite impressed by it. I'm not sure of the extent of Calibre/Sony integration, but there's definitely a lot of Calibre progress for the KT. (It made me go make a little donation!)
