I don't think that's what Thad is saying exactly, he's saying it would be the most likely. Keep in mind is that the focus is stuff not out on disc before, which likely means if WAC is to do a Looney Tunes set, it would be these one offs, pre or post 1948. I think what happened with the removal is no indicator or which ones would be put out should WAC be able to release the cartoons to Blu-ray
Now, in terms of character releases, it is possible that WAC would be able to sprinkle in the newly restored character based cartoons, but I would think the regular home release division would handle these. That said, it is bold to assume this, or try to guess a lot of this for that matter. Because a lot of the newly restored films, from any year, character based or not, is likely not out of the question. If anything, the fact that they're being reworked to have non-photoshopped titles is a good indication that there is interest in a proper release, but they don't have approval for this yet. With this in mind, it's too bold to immediately assume never
