A third though not-so-different Nokia Window Phone 8 device is pegged for release soon.
However, Arrow and a second device, the "Phi," have a tentative announcement date September 5 while the Atlas won't make it's debut until later this year.
Atlas is said to be a Verizon version of its straight shooting doppelgänger.
Atlas completes the rumored trifecta of Nokia Windows 8 handsets that'll be announced in the coming weeks and months.
Arrow is a Lumia device, too, sources say; and presumably the Atlas will be as well.
All device names are code names, by the way, though name changes at a later stage might be a miscue by Nokia.
When the carriers plan to unleash these phones on the world remains unknown, but TechRadar will keep you posted on any and all developments.
