I'm also having a hard time believing it!
Firstly because Verizon never received the latest and greatest first! That's always AT@T and I don't think we have any reasons to believe that is going to change now. As far as I understand, there is a deal between NOKIA and AT&T that gives them always the best devices.
Secondly, the LUMIA ICON is an excellent phone but is has last years specs (like the LUMIA 1520). Is NOKIA going to keep giving us phones with 6 months old specs? I thought they were all over introducing flagships that come with the latest tech inside. They did that last year with the 1520 but the same specs won't do it again. Competitors (Galaxy S5 and HTC One) already have Snapdragon 801 which is a slight improvement over the 800.
So, what I believe right now is that, apart from the design differences (which I think will be obvious... probably colourful polycarbonate and thinner), the phones will not be so different but the 930 will be slightly better. I'm hopping for a slightly improved camera, maybe a Snapdragon 801 processor, greater battery life and maybe some co-processors which will give it more motion detection and voice capabilities. But I don't expect it to be groundbreaking! No Snapdragon 805, no 2K screen resolutions, etc. Lets keep it real guys.
Wrapping up: I believe the LUMIA 930 will not be exactly like a LUMIA ICON, aside from the design differences I believe it's going to be better but not hugely better.
I wish it could at least rival other competitors flagships.
