In a letter from Kate Paiz on janurary 31 2013 she wrote:
Housing – I am extremely pleased to say that this year we will be tackling a major revision to the Housing system. In February and March we will be gathering information about how Housing should change, and then we’ll be releasing revisions to the system in the latter half of the year. We look forward to leveraging our new Player’s Council to help shape and guide the extension of this feature!
We are still waiting and the year is quickly comming to an end.
