According to The Verge, Verizon is going to be getting a variant of the Lumia 920 in April, and it will be a pretty nice upgrade. The upgrades include a switch to an aluminum body, a xenon and LED flash for the 8MP PureView camera, and the comes in thinner and lighter than the relatively bulky 920.
The 928 is apparently similar to the 720 in design—less curved than the 920—and feels significantly lighter than the 920. Its thinnest part is reported at 10.2mm (for comparison, an iPhone 5 is 7.6mm), and curves to get slightly thicker. An April launch would put the 920 approximately five months behind the 920's launch, and feature many of the same guts as its predecessor. So while there are certainly some really nice upgrades to be seen here, that's an awfully long wait for, essentially, a variant. [Verge]
