True, those features have little use. However the 4 USB slots are useful for playing mutiple instruments, it also run cooler than using multi slot adapters. But those features dissappeared a long time ago with the 80GB and 160 GB models. A 320 GB Slim is also slated for release soon.

Has anyone seen it in VMall?

The new 3.0 firmware will be released concurrently with the PS3 slim, which should provide a breath of fresh air for existing machines. Other new features of the PS3 slim include BRAVIA Sync, which allows you to control the PS3 XMB over HDMI through your BRAVIA TV remote, and System Standby to shut off the PS3 when the BRAVIA TV is off. Sony also claims this new machine will run more quietly than existing PS3 systems, which is good news for people who like to watch movies or have conversations in the general vicinity of their game console. There's also a Vertical Stand, which will retail for $24. Not so awesome is Sony's removal of the Install Other OS feature... farewell, Linux. We hardly knew thee.

Update: We've got press shots! Check 'em all in the gallery below, and be sure to pore over that to-scale comparo pic up top. There's one from above as well, which reveals that the new model is actual "deeper" than the PS3 fat.
