With tax free weekend coming up for us in 2 weeks, I was considering getting a refurbed Oct 2013 model with 2.6GH, 16GB, and 1TB. Those have been on the refurb site for some time. I noticed yesterday that most of the Oct 2013 models are gone. I also noticed that Adorama has an extra hundred off on newer rMBPs. Makes me wonder if this is just coincidence to Apple clearing out inventory to get ready to release a announce a new model in Sept that would either start shipping in Oct or not be available until Q1 if the Haswell chips have held up production. I was just thinking about what could be changed for a 2014 that might make me hold off and get one of them. There is already TB2 and USB3. I doubt USB 3.1 will be included. Wifi will continue with the AC spec. SD card reader should stay. 4K video support is there. The only candidates I can think of would be Hawsell CPU with corresponding chipset, 32GB of memory as an option, greater than 1TB SSD as an option. Unless the other options are introduced, it seems to me that the Haswell upgrade will be nice, but it is mostly about less power consumption and longer battery life. What say ye?
