Alright, the date is set for this year's convention:

from 2016-07-21 (Thursday) to 2016-07-24 (Sunday)
in Frankfurt am Main (and Bad Soden), Germany.

Please visit http://web189.102.hosttech.eu/w8/index.php?t=state - I updated everything (i.e. the hostel prices are the most recent ones). The main reason to visit that website is to keep track of the Status page, where we see who's coming and who not. And who's indecisive. It also helps organizing in who brings what.
