Harmy chose the Czech dub (not sure the criteria of this one over the 95 one). If you can convince him to drop the current dub in favor of the 95 dub, I'm sure it'll make the next release. But that's a big "if".

He has mentioned that the Czech SE dubs are technically better, but neither he nor I are interested in including despecialized SE dubs when there are already available dubs, even if lesser-quality, for the unaltered trilogy. One reason for this is that it's impossible to completely despecialize the audio, so original mixes simply always sound more authentic, and the second reason is that there is a certain nostalgia factor for the old dubs--to watch them as you first saw them as a child. For languages with multiple original dubs, there's always a bit of subjectivity in picking which is best. Hell, there are like fifteen Russian dubs (slight exaggeration), at some point you just need to pick one and run with it.

All of this doesn't mean you aren't free to add your own audio if the one we pick doesn't suit you. You can't please everyone, and I think Harmy and I also share the opinion that one dub in each language is typically adequate for global accessibility, and that including several audio options for any given language is up to another project (much like the Krieg der Sterne/German project does).
