How much improved will it be over the current rMBP apart from longer battery life? I know I know..there are no known specifications, but with release being in 10 days ( possibly ) I'm pretty sure most of people on here will have an idea. Before you comment, please realize that due to my region, apple products arrive here 2-4 months later after their release. So let's say, if the pro gets released late october in USA/UK, it will not arrive here before Jan 2014. I have a current old HP laptop ( broken battery, only works when plugged in LOL), and I'm heading college tomorrow, so I thought I might get myself a 8GB MBA, or maybe the current (old) retina. ( Will be paying full prices, there is no ref. service, and I don't trust used I want something to last).
