[Verizon Motorola Droid Turbo General] ChazzMatt:
For the upcoming 2015 models, let's look at recent history of last year's models...

Something like the U.S. Moto Maxx XT1250 (same device, same FCC ID as the Verizon Droid Turbo which PROVES it's the same device; same CDMA/GSM/HSPA/LTE bands as the Droid Turb XT1254 -- but with unlock-able bootloader) will show up on the smaller, regional CDMA/LTE carriers.

These are actual standalone carriers, with their own spectrum -- NOT Verizon MVNOs. But they have roaming agreements with Verizon, and share in Verizon's hardware portfolio but their models are sold under different names/model numbers. However, these devices are IDENTICAL to the Verizon models, due to having the same FCC ID. That's all the proof you need. ;)

The Verizon fanbois will be reluctant to admit it will exist because they like the believe the "exclusive" marketing LIES by Verizon. (Nothing about the Droid Turbo was exclusive to Verizon, except the "Droid" name -- because it's licensed by Verizon from Disney/LucasArts. Even the "Turbo" name was used by Motorola for another Quark phone.) This marketing lie was repeated verbatim by lazy bloggers/U.S. tech media who care more about Apple farts than anything Android-related.

These upcoming devices will work on the Verizon network just like a non-Verizon Nexus 6 -- and just like the XT1250 does.

When you find this device -- whatever the alternative model number/name is -- and buy it you will have to ensure it's unlocked from the carrier it's bought from since you will be paying full price. Again, this device will work on the Verizon network just like a non-Verizon Nexus 6. But it will be there -- just like the U.S. Moto Maxx XT1250 is available for anyone who wants a "dev" edition of the XT1254. ;)

The U.S. Moto Maxx XT1250 is not to be confused with the International Moto Maxx XT1225 and Moto Turbo XT1225 (see even the Turbo name is not exclusive), which are also Moto Quark phones but do not have CDMA bands enabled, and have a slightly different mix of LTE bands. All the XT1225 models are the same device, in spite of having two model names (Moto Turob and Moto Maxx). Same FCC ID across all regions, same SKU.

See, there were basically two Motorola Quark phones -- with two different FCC IDs -- released under THREE model names:

FCC ID IHDT56PK1:

XT1254 U.S. Droid Turbo/XT1250 U.S. Moto Maxx (identical device, CMDA/GSM/HSPA/LTE bands -- except for model name). The XT1250 will run on Verizon, with a Verizon SIM card. This device has LTE bands 2, 3, 4, 7, 13 enabled.

FCC ID IHDT56PK2:

XT1225 "international" Moto Turbo/XT1225 "international" Moto Maxx (identical device, GSM/HPSA/LTE bands, except for model names). This LTE bands 2, 3, 4, 5, 7, 17 enabled.

Of the two Quark models -- released under three models names (Moto Maxx, Moto Turbo, Droid Turbo) -- only the one with the model name "Droid Turbo" has locked down bootloader. The XT1250 U.S. Moto Maxx is basically the "dev" version of the XT1254 "Droid Turbo" if you can get your hands on it. (unlock-able bootloader, can be easily rooted, TWRP installed, etc.)

I don't see why that would change for upcoming models. You just have to research and find what you need.

This has been the pattern the past few years, and I don't see why it would change, especially since Verizon can no longer lock out non-Verizon devices due to FCC agreement. They don't have to "activate" those devices, but if you swap in an already-activated SIM card will work just fine. Just like the non-Verizon Nexus 6.
