Right this the info as far as well know at the moment:
The 60Gb US models come with the EE and GS for PS2 emulation. The 80Gb US models and 60Gb European models come with the GS only. The rumours are that the new 40Gb will come without the GS chip as well, removing 2 usb sockets and the card readers, thus allowing for the reduction of the motherboard.
Now we know that PS1 games are played entirely though emulation. Why can't PS2 games do the same. I just reckon, Sony need to create a software only emulator for the PS2 games. Surely this can be possible using the power of the PS3? If the EE can be emulated by the PS3 for the 60Gb Euro and 80Gb US models, then surely the GS can be emulated as well?
Anyway, memory card slots aren't important. The PS3 comes with a hard drive and I'm pretty sure you can pick up a USB card reader for under $10. Expect Sony to release one as well. 2 USB's are adequate as well. By the sounds of it, the Wifi is better as well.
If Sony cannot do this, then it WILL be a major problem for them. PS2 BC IS important to gamers.
