The main n41 channel was just moved up to 2639MHz this morning. This means that channel spans from 2589MHz-2689MHz. With Sprint B41 at 2501.5MHz, and TMobile B41 spanning 2508MHz-2548MHz. That leaves room for a 40MHz n41 channel. If they drop one of the TMobile B41 channels, they could easily expand that to 60MHz. This all in line with their permit filings which indicate a second n41 carrier of <=80MHz.
So this is new: 15x15 dedicated n5 in an area where AT&T has all of 850. Means they have as much low-band NR las T-Mobile does (way less mid-band though, even counting the occasional n2/66). https://twitter.com/iansltx/status/1527426642301403145?t=n2MWeh4psvOy-HMzvLYWBQ&s=19
