We just got an anonymous tip saying that their copy of Idol Master SP on UMD has firmware 5.05 on it. This actually makes sense, as it most likely allows the PSP to unlock “rewards” for PlayStation Home, as we had earlier reported.
We don’t actually have the UMD ourselves so we cannot confirm, however we expect this to be true. The question is… Will this firmware update be released via system update? Also, PSP firmware updates usually go hand in hand with PS3 firmware updates. Will we be getting a PS3 firmware update as well?
