DBZ movies: yay or nay?

[Kyo28]

I've been tempted to get the DBZ movies on Blu-ray (released by Funimation), even if it's just for nostalgia's sake (some of these movies, I even used to own on LaserDisc).

• However, I've noticed that for a blu-ra release, the audio is subpar. I mean, I know these movies are old but Dolby Digital 1.0 is the best they could do?!?
• On top of that, I've noticed the original Japanese title screens are absent and replace by crappy English title screens.

I have to point out that all my anime, I want to get with the best possible Japanese audio track, in its unaltered Japanese form (no English inserts). I don't care about English audio or subs, so I just buy US releases because they are cheaper, provided they offer the same content as the Japanese version.

So, I was going to buy these US releases because they're pretty cheap, but considering these issues, I'm thinking of waiting for a possible Japanese release. Sure, it'll be more expensive but at least I'll have the movies in their original form (with Japanese title screens) and hopefully with a better audio track.

Any thoughts on the matter? Do other fans agree with the issues I have with these releases? Any chance of seeing a Japanese release soon?
