Looks like PSP will be joining in on the Home fun shortly. Japanese games site Gpara.com reports today that an upcoming PSP title will feature Home Rewards support.
The title in question is Idol Master SP, Bandai Namco's PSP version of its popular idol raising simulation game. Set for Japanese release on the 19th, the title will offer Home Rewards support, giving players Home items as they progress.
Home will also see Idol Master SP items and even an updated Bandai Namco Carrot lounge featuring Idol Master themes starting this Thursday. For screenshots, see the original Gpara article.
Idol Master is a Japan-only game, so this particular facet of Home will likely be accessible only by gamers in Japan.
