Well if anyone lists any Apple product as being at the end of its life and that site isn't Apple I would take it with a grain of salt. However, I do not think the shuffle will be back in the original form ever again. I think it'll be enhanced somehow. They brought us the shuffle and that was amazing. Then the nano which proved they could do it and do it with class (and a screen). What's next? Shuffle with a small screen? or 1"x1" square? You never know.
I would still buy one. I use mine all of the time as a thumb drive and at the gym. Even with a $200 nano I couldn't see myself bouncing around with it. The shuffle I pretty much carry the attitude that if it breaks it breaks.
