The PS2 is the greatest selling console in history with over 110 million units sold worldwide. It's still outselling all current next gen consoles. I don't know about you guys, but my PS2 is dying. I don't like the idea of buying a new PS2 because the PS3 doesn't do BC. I'm going to hang around the stores and see how this 40gb PS3 fairs for X-mas.
I know it sounds cruel, but if Sony wants to sell more PS3's they need to cancel the PS2. Microsoft did that with the Xbox, when they launched the 360. If people can still buy the PS2, they will, in fact according to current sales they still are.
