In order to make its target of pre-Christmas release date, Sony is cutting some features from the PSX, its souped-up version of the PlayStation 2 that comes with a DVD burner and a hard drive for recording TV shows like a TiVo. The first to go from the PSX: the ability to playback CD-R and DVD+RW discs and MP3 music files, its Ethernet port (a move which baffles us), and a cut back in the speed of its DVD burner from 24x to 12x (which is still fairly fast). No word on whether Sony might reintroduce some of these features when the PSX goes on sale in the US, but it seems doubtful.
