The previous 50% off sale was the week prior to S03E01, while this one is the week prior to S03E03. ArenaNet rarely does sales themselves, so you should assume that this is the last one of the year. Assuming the trend of sales being linked to the episodes, the next sale would be ~4 months away with S03E05. After that, I wouldn’t count on seeing any more sales, as the next expansion would likely be less than a year away, where they’ll have to again offer refunds due to their 1 box model.
For Black Friday, they’ll likely be doing a gem store sale as they’ve done in the past.
