I'm going around taking screenshots of the things I have on my walls that I will have to take down before replacing the partitions but I'm really excited to finally have matching partitions and doors. I will even save a few slots because of having to hide the partitions that didn't match just to use the doors.
Like Khryseis said, they never gave a firm date while the furnishing limit expansion was 7.2 or 7.3. Now with 7.2 almost here, the furnishing limit looks to arrive at 7.3 and for the interior size update, it looks to be 7.4 the earliest but could be 8.0.
