In what appears to be an interesting change from being called 1330 (phablet successor to 1320) there may instead be a 640XL. Reflecting perhaps the 640 specs but in a larger frame. Could this help out with the confusing numbering between generations?
Tom Warren has previously tweeted expecting both the 640 and a 1330 (640 XL?). Specs are pretty standard for the 640 – a 5″ device. How much bigger should a XL version be?
Cheers Alvester for the tip!
