In 2015 and 2016, we ended up with more than three hundred videos in each SPIEL playlist, so we probably have even more than sixty in the pipeline. I have several on my camcorder, for example, and someone else is processing all the day-long feeds that we recorded at SPIEL '17 and chopping them into individual game segments, feeding the parts to me bit by bit on our YouTube channel so that I can add thumbnails and publish them. We ran into a slight delay ahead of BGG.CON due to hard drive backup issues that made it tough to pull off files, but now we're hobbled only by the massive quantity of videos.
I'm still not sure whether this publication schedule makes more sense than dumping a few hundred videos on BGG and YouTube all at once, but in any case ideally we'll finish everything before Christmas to give us (and you) a break before we head to the Spielwarenmesse fair in Nürnberg, Germany at the end of January 2018 to start the convention cycle all over again...
