I was thinking of grabbing a next gen MBP after the Conference but it appears Apple is waiting on sufficient supplies of Haswell Chips before they release it. In the meantime I upgraded my 17" 2011 MBP (Intel Core i7-2720QM 2.20 GHz) with 16GB of some very fast Corsair memory and a 256GB Samsung 840 Pro SSD. I've gotten a very nice 10,250 Geek Bench 32 bit score. More importantly it just performs so well now. I've had some reservations on going to a 15" retina display as I honestly love the hires 17" matte screen on my MBP. I've also have been holding on to Snow Leopard which I love. Now I can enjoy my MBP with it large screen and the simplicity or SL for a while longer without much of a performance penalty compared to the current MBPros. Anyone thinking about taking the plunge, I highly recommend it. It's easy to do and the cost is fairly minimal.
