I'd happily downgrade my LE when he does, but to quote the designer when I asked him last week (whilst on the topic of modding MET-Pro with his Total Lightshow):
"Yes, I was doing TWD, but never really got a lot of traction from the crowd, so I let it slide. I was really happy with getting Horde to work too! I may revisit it, but I have long since sold the game as well, so it would involve me getting another one in. I won't write it off completely, but it will be a while if it ever happens."

...So don't hold your breath! The pulsing red really is superb.
