I don't see how the november PS2 redesign is going to solve this problem. People already have a PS2, but don't want to have to keep it under the tv with the PS3, having loads of wires and plug sockets used, not only are people annoyed about the lack of bc, but not being able to sell their PS2's mean they can't put money towards the PS3, meaning even less sales.
I see what your saying, I'd also like to think sony will bring out say a 120GB model with BC again in the future.
I'm just happy I got a 60GB.
