The History of "Premium Windows Phones"
November 2012
Nokia Lumia 920 - Sold ok, but not in the numbers that were expected (AT&T only US)
Debuted at $199 for 32GB on contract - Currently $250 no contract
HTC 8X - Sold poorly across 3 carriers - special version for Sprint is still available (8/13)
Debuted at $199 for 16GB on contract - Currently $150 no contract

Nokia Lumia 925 & 928 - None of this line sold well - the 925 (US) was crippled with 16GB of internal memory and the 928 was doomed by the Icon rumors that hit almost the same time as its release. The T-Mobile 925 was EOL'd after 6 months. AT&T followed shortly there after.

Lumia 1020 - a niche market phone that sold well to phoneographers - but that's it. Limited storage (32GB no SD) made this 41MP shooter almost worthless to the average vacationing consumer. Lack of USB OTG made dumping photos impossible on the go, unless you took your computer with you.

Lumia 1520 - the phablet arrived... That is all. The release of another "exclusive" device on AT&T came with a ton of fanfare, but even today's commercials show the state of wireless in the US... You know the one that has the guy walking into the AT&T store only to have the person say, "Yes, we have the new iPhone." To me, the 1520 failed because all it did was 'upscale' Windows Phone to a larger format. I couldn't get more tiles on screen. I couldn't resize text to be smaller in the browser. Everything was just bigger - and for most users, the 1520 was too big.

Lumia Icon - Already EOL'd by Verizon...
August 2014
HTC One M8 for Windows - The M8 has been beat up for the reset issue, having a lackluster camera and not being as 'good' as a Lumia. The fact is, the M8 is a gorgeous piece of hardware with a not-so-great OS on board. Yes, I said that. The Android version is about as good as a phone gets and the Windows Phone version is pretty close to it, but not there yet.
Here's the issue as I see it...
Microsoft is selling a ton (and by ton I mean 10 million handsets in 3 months vs. Apple's 10 million in 3 days) of sub $100 handsets. The problem is that people are buying them to tie them over until they can get 'a real phone'. Trust me, my nephew did it and my nieces did it. The 52x series was cheap and worked, but they got their iPhones back ASAP. Microsoft isn't selling the Premium handsets like they thought they would. It's time to decided if they are going to move forward or if they are going to just release services for everyone else.
Their newest lineup, due out soon will have the mid-range 830 (AT&T) at the top, the 735 (T-Mobile) heading up the middle range and the 635's floating in the $100 market. The 530 series will be the sub $100 level device and be a favorite of the non-contract crowd. I don't see Sprint being a player with Windows Phone much longer since the 8XT didn't move well and they were so slow to adopt in the first place. Verizon has the current flagship in the M8 and only time will tell how long that device holds on. Hopefully, by relaxing the hardware standards and using the M8 as a test case, some of the Android powerhouse devices will just get ported to Windows Phone. I think that's the only chance there is of having any more premium devices roll out.
