It seems like haswell rMBP's won't be coming out until september now. I've been waiting since before WWDC in June for a refresh, and I don't want to wait two more months for something that may or may not happen. I have the educational discount and I don't want to miss out on the $100 gift card for the back to school promo. My problem is that I want the most for what I am going to buy. Are the HD5100 graphics really going to be that much better? Will the battery improve as much as the airs did? I want the 13 inch model, but I'm not sure if the graphics of the current hd4000 can handle what I will be doing (video/photo editing). Do you think I should wait for the haswell update or take advantage of the back to school offer?
