Sounds like the typical Apple strategy
According to Macrumors and OSXDaily, a new Macbook Pro has been in the works and will be released on June 11th at the World Wide Developers Conference (WWDC). From the current rumors circulating the internet, it seems like the new MBP is going to follow all the typical Apple trends. It's going to be "thinner and lighter" and will probably feature the retina display that has now become a part of the iPad, iPhone, and iPod Touch.
However, if the retina display is to come to the new MBP, there is some doubt surrounding what the cost of the new laptops will be. Retina displays are certainly not cheap.
According to Richard Shim, DisplaySearch Senior Analyst via Macrumors.com,
a Retina 15.4-inch display at 2880x1800 resolution for a density of 220 pixels per inch (ppi) currently costs approximately $160, a $92 increase over Apple's estimated cost of $68 for the current display in the 15-inch MacBook Pro. In the smaller 13-inch MacBook Pro, a Retina display at 2560x1600 costs $134, a $65 premium over the display used in the current model.
As for graphics, Apple is going to rely on Nvidia for the graphics chipsets for the new Macbooks, as opposed to the AMD graphics cards they have been using in previous generations.
