According to the official Japanese SCEJ site, the current closed Home Beta is due to end in a matter of weeks, presumably then opening up the final 1.0 version to a wider public. Additionally, here’s a list of companies that have signed up as partners for Home, providing content, spaces etc:
Walt Disney Japan
Nippon Ichi Software
Bandai Namco Games
Home has a major presence at TGS this year, as can be seen by these photographs from the show.
