Right now I am leaning towards getting the new 15 inch rMBP. However my concerns lie that I would prefer a 13 inch laptop but the air just doesn't cut it for me with performance (gaming/video editing). Would it be worth it to get the 15 rMBP now and then sell it when the 13 inch rMBP comes out hopefully in October? How much do you think I will lose? Also Do you think the 13 inch rMBP will have a dedicate GPU?(this may be the deciding factor)
