Houses will be getting upgrades to the safes, changes to add-ons to make them more useful and things like farming plots. In addition we will be making houses dynamic so you can place them anywhere, with of course limitations based on holdings, mob spawns, dungeons etc.
Can we see some love for people with house vendors especially the people who paid top dollar for them before they were craftable. Maybe something with a tie in to the market system.
For right now house vendors will remain separate, there was plans to tie them into markets initially but a final implementation direction wasn't decided for this patch.
