Yes, you are indeed delusional, which is a form of koo-koo. Here is how I know they are likely to never sell it, or at least in the near future:
I was actually at my local Tmo store yesterday, switching my family back from the evil demon-spawned Cricket, and of course was getting my 4 phone numbers ported over to Tmo. The only phone I had with me was my phone, the original Nexus 5. One of the kids (all young 20's, so kids to me) working there said, "Did you know they are releasing a new version of your phone? It's called a 5x" I said yep, I've got one in a box waiting for my son for his birthday in a month. Jaws dropped, one of them grumbled something, and then the same kid said, "And did you know they also are releasing a bigger version called the 6p?" I said yep, that one is for me and it should be delivered to me in about a week and half at most. At that point they all said versions of "Aww man!" and shook their heads, and the guy who had been talking (the store manager) said, "Can I ask you just one favor please? When you get the 6p, can you bring it by so we can see it?" When I said yes, they practically squealed in delight.
They are all expecting me to show up two weeks from yesterday at around 5 pm, and will be severely disappointed if I don't. These are people not expecting to have this phone in their store anytime soon to play with, and obviously with the discounts they probably get on buying Tmo phones won't run out to buy their own unlocked phone.
Oh yeah, and the manager said he has been told the 5x and 6p will definitely have wifi calling on Tmo.
There, I think we stick a fork in this thread now, you are welcome.
