He didnt say they werent going to do it at all. He said they were not planning to do it any time in the near future. Most likely due to other more serious priorities.
Like the housing issues itself with an expanding population and very limited housing plots, glamour system updates, armory chest updates, increasing furniture is a huge task and a huge load on the servers. So they will likely do extensive testing on the back end to make sure the servers can handle an increased load.
Given the size of this expansion and what is shaping to be a massive 5.1 id be willing to bet the earliest they may even consider it is 5.3 and we probably wont see fruits of that til sometime after that maybe 6.0
