Hello! First post. I've been reading the forums, especially similar questions, what are the improvements on the current MacBook Pro Retina over the soon to come MacBook Pro Retina? Current Model: 15-inch: 2.7GHz Retina display 2.7GHz quad-core Intel Core i7 Turbo Boost up to 3.7GHz 16GB 1600MHz memory 512GB flash storage Intel HD Graphics 4000 NVIDIA GeForce GT 650M with 1GB of GDDR5 memory Built-in battery (7 hours)2 Is the model that is coming out soon that much of an improvement? If it's not and it is coming out around October, should I really wait?
