I've been in the market for a new Macbook pro, and have been doing some price comparisons of used models on Amazon. It seems like there are new Macbook Pro models available for preorder, but I haven't heard of any changes/updates from Apple's site. I also looked at their store to see if the new models were listed there, but I'm not 100% sure since the hardware changes seem to be minimal.
Have new models been announced/released? If so, what upgrades have been included?
