Traditionally, new generations of devices have been pushed out late in the year.
Generation 1 (Windows Phone 7) devices were released on October 21, 2010.
Generation 2 (Windows Phone 7.5) devices were released on September 11, 2011.
Generation 3 (Windows Phone 8) devices were released on November 2, 2012.
Based on this, I expected Generation 4 to be released around October, but this doesn't really seem to be panning out currently. I'm starting to believe we'll actually see them in early 2014 with the release of Windows Phone 8.1.
Also note that phones like the Lumia 625 and Lumia 925 don't really constitute a new generation of devices - they're "refresh" devices, at best, and the Lumia 925/928 are "carrier variants" at worst.
