Some tidbits about Lumia 1520 from our sources. First of all there will be an announcement event for the device during 4th week of October and it will be followed by launch during 2nd week of November at AT&T (9th-10th). The device is not going to come cheap and will cost same on-contract and off-contract as of Lumia 1020’s initial price.
So, on-contract pricing will be $299 and off-contract $699 for the 32 GB version. A 64 GB version is also in works but AT&T may not carry it initially.
We know many have reported similar time frame for lumia 1520, but it is always good to validate it.
