Retroid specifically said the 4 and pro being released at the same launch window was in response to the backlash they recieved from doing what you described. They can't possible make that same mistake again. I hope.
Retroid has revealed various details about the Pocket 4 and Pocket 4 Pro, both successors to the popular Pocket 3 Plus. While the pair look similar, Retroid has distinguished them by including different chipsets, RAM configurations and video output options.
