Nexus 6 to get T-Mo's WiFi Calling?

hopefully it'll be released on Android L therefore trickle down to other android phones as well.
 
I'm not sure I believe in this story yet, but there is an article on 9to5google.com that the claimed a T-Mo rep said they are working to get T-Mo's Wifi Calling to work on the Nexus 6.

If you like, you can skip past a good deal of- conjecture on sites working off of hearsay and assumptions, and go straight to T-Mo's press release which says explicitly that "100% of new smartphones in T-Mobile stores will be Wi-Fi calling and texting capable."

The only question you have to consider for T-Mo now is whether they will be carrying the N6 in their stores. If so, it will support their WiFi calling/texting. If they will not have it in their stores, it may or may not.

And if it does support WiFi calling/texting as some function of a change in the Android OS with Android L, it's highly possible that owners of earlier model Nexus devices may be able to enjoy it as well.
