The current resolution of the iPad Mini is 1,024 by 768, and if the Retina display is added, the resolution will increase to 2,048 by 1,536. The current cost of a startup iPad Mini is around $188 per unit, which if the Retina display is added, will become roughly $200 per unit. The existing devices, which sport a 7.9-inch display, are compatible with applications created for first and second generation iPads. However the new iPad Mini should have a 7.9-inch Retina panel.
The current sale price of an entry level 16GB iPad Mini is $329, which might be revised to compensate for the change in production cost. However, with both Samsung and Acer poised to launch their own versions of 8-inch tablets, Apple faces stiff competition and the company might have to stick to a competitive rate. The launch date of the Apple iPad Mini is still unknown and is open to rumors of all sorts.
