SCEA has confirmed the news to 1UP and refused to specify a new release date, even one within a "end of 2007" timeframe. Here's their official comment:
"In an effort to provide consumers with the most robust experience on the PlayStation 3, and access to a diverse catalog of downloadable content, the date of SingStar PS3 has been pushed back. We hope to have a new launch date confirmed in the near future. With a strong lineup currently available for the PS2 including SingStar Rocks, SingStar Pop, SingStar '80s, SingStar Amped and the limited edition SingStar Pop Ceramic White PlayStation 2 bundle, the franchise will continue to provide fun for the entire family this holiday season."
