Either way, Nokia's naming sucks. The people deciding on model names should be fired. It lacks coherency or any real meaning. The Lumia 510, 610 and 710 are based on WP7 hardware, but the 810 is WP8 hardware. 1020 sounds like it should be a next generation device, but the internals are no different from the 920. The 720 sounds like a higher-end device than the 620, but the internals are almost identical and only the later ships with a world wide license for HERE Drive. If they built a 930 using the GDR3 chassis spec (as we both suspect they will), it would be more powerful than the 1020, but that won't be reflected by the model number.
Nokia's naming scheme, which is just arbitrary enough to be useless, is responsible for thousands of posts along the lines of : "this is not a worthy
upgrade to the Lumia 920". Even on this forum, where the most informed WP users hang out, such threads were not uncommon. It was so bad that Nokia had to come out with an official response explaining that the 925 is simply a "new expression" of the 920, which would have been completely unnecessary if handled more intelligently:
Instead of
| | |
Lumia 925
| Lumia 920S
| making it instantly clear that this isn't an upgrade, but a variant of the 920 (S=svelt)
|
Lumia1020
| Lumia 920 PureView
| or any other suffix emphasizing the camera, but ultimately a variant of the 920
|
Lumia 928
| Lumia 920V
| V for Verizon, also a variant
|
Lumia 521
| Lumia 520T
| T for T-Mobile, also a variant
|
IMHO that is still far from adequate, but it's a start.
