I think the restoration of the laserdisc sources is like 99% of the work and upscaling it to 'fake' anamorphic only 1% work, so it seems reasonable to make both LB and anamorphic versions, when the time comes.

In any case the X0 will be much much better than the GOUT. Lucasfilm appear to have applied a vertical blur filter trying to hide jaggies and a rather poor deinterlacing job, so the GOUT does not even have the vertical resolution of standard letterboxed NTSC and this is very visible in some scenes where some of the vertical detail is completely gone. And in this respect the GOUT really looks like crap, upscaled or not (IMHO).

I trust the X0 team already done proper deinterlacing and even removed some of the jaggies 'by hand' and this is of course a much better base for a fake anamorphic upscale.

Next step would be to combine the horizontal resolution of the NTSC X0 with the vertical resolution of the PAL laserdiscs and gain some 19% in real vertical detail.
