Slides from AdDuplex show three Lumias coming from Microsoft – the 4" RM-1099, the 5" Lumia 640 and the 5.7" Lumia 1330. The Lumia 640 and 1330 will be headed to AT&T in the US, but have plenty of other versions for a worldwide release.

Note that AdDuplex is an analytic firm that keeps a very close eye on the Windows Phone market and also what phones are upcoming.
