This has been a strange path for HTC in regards to Verizon. First, it was rumored that Verizon would be rebranding the One
as the DROID DNA+. Then, we heard that rumor wasn't true, and that the One would be delayed on Verizon
for "testing". Now it looks like the HTC One will be released on Verizon with that name, but it will replace the HTC DROID DNA on Verizon shelves. Or, at the least it may replace the DNA on Walmart shelves.
The leaked document comes from Walmart, and explicitly says that the HTC One will "launch in March", which seems to contradict the idea of the delay on Verizon. But, it also says that the HTC One will replace the "HTC DNA" on Walmart shelves.
This makes sense though, because the HTC One is HTC's flagship, and that's kind of part of being a "flagship" phone is that there shouldn't really be any other options from the same company that are aiming at the same user.
