Microsoft has announced the Lumia 640 and a XL version, at Mobile World Congress, one with a 5-inch screen and the other sporting a 5.7-inch display.
Nokia's approach to marketing the phones and naming them has been interpreted by some as a reboot of the budget Nokia XL program.
These phone ran a forked version of Android, with X+ rocking a smaller screen and the XL blessed with more display to play with.
This was the first time Nokia had gone down that route, and they didn't pursue it in many countries. Only those where less higher-end Nokia phones were sold.
uSwitch went as high as we could to get an answer to the question: is the 640 XL a reboot of the Nokia XL program?
Marketing Director for Windows Phone, Greg Sullivan said: "No, it's a new device that was created and is a part of the Lumia line."
We put it to Sullivan, then why isn’t the 640 XL given another product number, as the first time Nokia (now Microsoft) ever used XL was for the Nokia XL forked Android phone?
"There are obvious parallels in the naming convention in the nomenclature.
"In terms of the product itself, it's a new Lumia device."
That puts to bed the rumours and speculation surrounding the phones, although we can’t help wondering if the hardware of the 640 XL was the next step in the Nokia X series.
Only time will tell if the truth comes out, and if the program was recycled with Microsoft distancing itself from a rival operating system.
