DID was bought by Ocean, which in turn was bought out by Infogrames (now Atari) and they closed it down.
The DID guys all got jobs elsewhere. I've worked with a few of the guys from DID as some of them came to work at Warthog in Manchester where I was a coder (Phil Mervik, Jon Radcliffe, Jon Spencer). From what they've told me about the Amiga version of TFX is that it was bugged to f*** and this is why it was never released other than as a magazine freebie.
I suppose Atari still hold the rights to all the DID games and IP.
