There was little research to be done, most threads here that were about the subject whether Apple would update their laptop line, said that there probably were no big changes to be expected.
Apple took us a little by surprise by upgrading their laptops quite a bit. My MBP is also just 3 months old (and a little damaged due to a drop, left corner dented) and I would love the better screen, longer battery life and SD card (specifically because I use my MBP for photo/video editing)
That's just the way it is. Tech evolves, live with it. Or sell and upgrade.
