Is there a second-generation Airport Express 802.11n? 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?
Not yet on a 2nd gen 802.11n Express.

Apple has published four different manuals on the Airport Express:


AirPort Express 802.11n (1st Generation) - Setup Guide


The three expresses prior to that were not 802.11n so perhaps that's where the three previous generations (and the 1st and only newer generation names have come to be) A tad confusing, no?
