I have no news but point out this is now in the same boat as Fredericksburg, Lubbock, Clovis (NM), College Station. A step up from a hole in the map, but don't hold your breath.
Both Denison, TX and Henryetta, OK show up as proposed for 2020. Either would be a big help for travel between NE Oklahoma and North Texas. But I agree, don't hold breaths - even absent pandemic associated roadblocks.
We're in November now and no updates. I have called Tesla Support twice in the latter half of the year and they are unable to see any detail. Definitely much needed. Henryetta is an added 20 miles out of the way for North Texas drivers but we'll certainly take it over none. That along with Denison would ensure long distance in all seasons.
