So after reading this here https://www.macrumors.com/2015/08/03/imacs-faster-processors-improved-displays-kgi/ would this mean that sometime at the end of the year that the entire Retina iMac line would have an improved display from what it currently has? I currently have the high-end 27" Retina iMac that I had picked up earlier in May but now after reading that the new ones could have a new improved display its making be debate the fact if I should sell my current machine to pickup the new one. Any input on this guys? and also when do you think the release / pre-orders begin for the said new machine?
