Good morning Savannah. You hit on one of the most commonly misunderstood words there is..... "biweekly". In most cases, biweekly means "every other week", but many people interpret that word as meaning "twice per week". When I first saw BIEL's announcement that they were beginning biweekly updates, I was afraid this would happen.
It's very possible that they did actually mean twice weekly updates, but I would bet that they are intending them to be every other week, and that would mean we should expect our next update next Thursday.
