“SingStar track compatibility across PS2 & PS3 is enabled via the Disc Swap feature,” says the piece.
“While playing a SingStar PS3 disc, at the song select screen, hit the [select] button to swap discs and play the songs from the inserted disc. The songs are not saved to the hard drive.”
The feature will be delivered via a free game update later this year, apparently, and will work with all current SingStar PS3 discs. “It will also be included on future SingStar PS3 discs releasing next year.”
Also, your PS3 won’t need a firmware update either.
Well, glad that’s cleared up.
