Who's saying they won't? So, at some point they may or they may not... but it's unlikely.
First... the main problem of the redesign is attachements like the HDD. Attachments become no longer interchangable... which was suppose to be a big selling point of the detachable HDD.
Second... the costs involved in the redesign. Yes, eventually a smaller product saves money... but think about the RD involved in the redesign and the setup of a new production line.
Will the new design actually be worth the cost savings and totally segmenting the current user base?
