Hi all: I am coming back around to Apple again after a long stint with PC laptops. I am interested in a near-top-of-the-line Macbook Pro with Retina display, 15". What I'm concerned about is if there are: a) any newer models rumored to come out in the next few months? b) if there are any rumored price cuts coming in the next few months? Any advice you could give me on these topics would be greatly appreciated. Thanks!
