I'm in the market for a new Airport Extreme as I currently use an Airport Express (bought 9/2012) with a 2nd gen Airport Extreme as a wireless extender. I find that most of my devices are favoring the 2.4 spectrum and I get daily pauses in web use and/or streaming that makes me think my current setup is not ideal. With an iPhone 6 and Retina Macbook Pro, I should be able to take advantage of the 802.11ac and use a new Extreme as the main station with the Express acting as an extender. The only issue I have is the current Extreme was released in June 2013 and there are other routers coming out with newer (better?) chipsets for the wireless signal and maximizing throughput (i.e. MU-MIMO) Any thoughts on where the current Extreme stands and thoughts on a new one coming soon?
