US Tour with High on Fire?

The ticketmaster listing says that HOF is playing at the HOB Chicago show. I didn't see anything about Nachtmystium although it wouldn't surprise me considering they are based in Illinois. And yes, HOF owns. Matt Pike is one bona fide badass guitarist.
 
The other bands mentioned don't quite fit with Opeth, imo.
But at the same time, who does?

I think an Opeth/Meshuggah tour would be nutty. They like each other's
music, they're both Swedish, and they both rule, so... why not? :D
