The big four features in the next update will be the player career/education system, home buying/renting/upgrading, the new face portraits and 'OnlyFats', which will be an in-game feedism website that you can sign up to & sell content on. OnlyFats will be populated by procedurally generated models from around the world who will gain and post content throughout the course of the game. You (and/or any girls you convince to model) will be able to create your own content to try and beat them in the leaderboards & potentially earn lots of money.
I haven't started work on home upgrades yet, so what it'll include is still up in the air. But I can add a swimming pool upgrade, no problem. Feel free to suggest any other stuff you'd like to see!
