Ok well, itís still not out. It was previously reported on sites like IGN that users can expect the US firmware version 2.0 on August 12th. The last I checked itís August 13th here, meaning it would be the 12th in the USA. However upon further investigation it seems that IGN and a few message boards are the only ones claiming this release on August 12th. Sonyís US Press Release site mentions nothing about US version 2.0 anywhere.
Furthermore, the US Sony System Update page still has 1.52 as the latest system software version. We still have plenty of day time left, maybe Sony is just taking their time.
