Once new FX are being done in CGI, it would not cost that much more to render them in 3D. Just a second render pass from a different camera location. Of course converting the filmed live action footage will be much more difficult. I wonder if this technology they claim to have is any good or if we're talking Clash of the Titans issues. Either way, it's possible that the 3D channel is putting up money to convert shows and that is being used to fund TNG-R the same way HD-DVD was used to fund TOS-R.
