So if we look at the above table from the MS site, Phone 7 was upgraded to 7.5 (Mango) then 7.8 (Tango). Tango was released after Phone 8 was released and is supported through September 2014.
Phone 8 (RTM) was released in December of 2012 and is supported through July 2014. We know Windows Phone Blue is being released sometime this fall and will most likely be Phone 8.1 or 8.5, current handsets should be able to be upgraded to Blue, which would have Blue supported through April 2015 on the current Handsets. The only issue we might see is that at some point the required hardware specs will outpace what current handsets can support, such as Quad Core or HD+ Displays.
I’m confident that the higher end HD phone are good for one or two upgrade cycles but the lower end phone with the older resolutions may be in jeopardy of missing out on later upgrades.
