Looks as if a fair bit of information on Home will come to light during this year's Game Developers conference.
On February 21, Sony is hosting a Home tools and support presentation with developers. The presentation will cover an overview of the current Home Tools features as well as feature roadmaps for the future.
In addition, Sony plans to walk developers through the process of creating a Home space and show how to create 3D mini-games within the Home service.
They'll also take a glance at a feature called Home Interactive Item creation. More to come as it's available!
