I mean, in theory, if there was no summer/autumn(?) CBB, we could be seeing a 13 week series. It's very unlikely, yes, but BB13 was supposed to be 13 weeks (am I right in saying this?) but was cut to 10 to accommodate CBB10

With no summer CBB, a 13 week BB could be possible
Alternatively, it could we get 3 weeks extra of BB, which brings it to like, 10 weeks lol
Or maybe this just means we get 6-8 week BB
