I might be wrong on both counts then
I thought Halloween was W39, not W43. So there's hope for W39!

As for them being forever sold out of FW, I would generally trust what
DVC says in response to specific inquiries vs. the general/shared knowledge we have here on the forums. But I would be very surprised if they were already sold out. In theory they could sell 126 fixed weeks (based on the 35% rule and 360 cabins), but they've only declared ~63 cabins. So if they were sold out, they'd somehow have 2x the occupancy of what they declared.
Maybe they put the 'sold out' line a lot lower than 35% of 360...?
