Yup - NewTekniques officially went belly up. (About 3 issues after LW6.0 was released). This eventually morphed into NewTekPro which released 7 issues - issue 8 is currently in limbo as I mentioned above - unfortunately this has now been in limbo for around 6 months or more (and I've still got an unfulfilled subscription!) - it's just not worth the hassle trying to cancel these things...
The other mag available is Keyframe (I believe this is now edited by none other than the able Mr Dan Ablan!).
Websites are as follows:
