Wondering same myself, Mr. Lustig.
Apparently 21(9) has been wiped from Train Status; who knows if it ever continued its journey. 22(11) is marked Status Unavailable from SAS and shows "Sold Out" (sure, hey), so both 21(9) and 22(11) would appear to have been annulled.
I had more than a passing interest in this. I'm going to Dallas next following weekend, and was "just curious". One Roomette open in each direction; RT $810.
I'll just pay what I must and "tuck it out" in the Friendly Skies.
addendum:

So it would appear 21(9) made it to Longview. I guess it will be deadheaded to Ft. Worth to handle 22(11). As of a few moments ago, the website shows open seats.
