In late 2011 there were refreshes to Airport Extreme and Time Capsule. At the time there was speculation that there would be a second generation of the Airport Express 802.11n model.
I'm in the market for a new one but I can't find any solid evidence that there was actually a new model ever released. I notice when checking my current model's serial number that Apple specifies it as AirPort Express 802.11n (1st Gen), which makes me think there's a later generation, but again I have no actual info on it.
Does anyone have an answer on this?
