A good deal of the early summaries were made as placeholders summarizing the content of episodes, some loosely based off of the official but too-short ones given by DEEN. The "advance" mini-summaries for episodes yet to air are pretty much due to spoilers from Comic Birz, which Japanese fans leak on 2ch. Sometimes there will be someone on Livejournal that will post the spoilers in a locked entry too!

Right about now, what's known about the next four episodes is that we'll be getting more Spain and Chibiromano, SWEDEN, Finland, Japan, Greece, and Germany. 18 is apparently the "Running away with Su-san" episode unless there was an ordering error (it happens).
