There is a heck of a lot that we still don't know about the recently announced Singstar Volume 2. We don't know if the title will simply add songs onto the store, or if the game will need to be inserted into the PlayStation 3 to play the songs. We also don't know whether the songs on the pack will be released on the PlayStation Store either. We weren't sure whether Singstar Volume 2 would come with USB or wireless microphones, but a listing by retailer Top Shop seems to indicate that Singstar Volume 2 will come with USB microphones and not wireless microphones. When Singstar for the PlayStation 3 was first announced it was revealed that wireless microphones were on the way. Months and years later we are unfortunately still waiting for these microphones.
