I did find this segment of the interview interesting....
TrekCore: Do you know if they’re going to be coming back to help with future seasons?
Denise Okuda: We really don’t know. If they came back, we would be thrilled again. Both the artists and the folks at CBS Digital and HTV, we have a great working relationship. We enjoy the enthusiasm. Mike and I feel so fortunate to be on this project and part of the team.
Mike Okuda: If we were fortunate enough to work with them again, we’d be thrilled.
In my opinion the original artists were too concerned with staying faithful to the original effects and they are partly to blame with not keeping in line with the earlier work done on CBS-D. It seems that CBS is on the fence about inviting them back for seasons 4 and 6. Maybe it's because they too see the difference of quality between seasons 1 and 2. I hope this is the case, because I'd much rather HTV Illuminated worked more closely with CBS-D than the old gang, after seeing some of the screenshots for season 2.
