So I just watched the whole webisode series they released before the new season. It's very good, probably the best internet stuff they've done.
It takes place more or less during the same time as the new episode and features Gaeta and an 8. There are definitely some important plot points for the former's character, and by the end you'll have an inclination what's taken place will tie into the newer episodes.
The earlier link someone provided doesn't work for us in the US, so here ya go:

I highly recommend it.
