I might be interested, but I hear (including in this thread) that the subtitles for the Japanese audio track are inaccurate as they're for the English dub. That would hold me back quite a bit, as I find the English voices for Naruto too annoying. I have watched a lot of anime English dubbed, some when a perfectly fine Japanese subtitled track is on the same disc, so I'm not a "must be Japanese!" guy, but one bad voice or script error will send me to the original Japanese track. In this case they're both the same, one I'd get script inaccuracy and annoying voices, the other I'd get the same script inaccuracy while being lied to about what the characters are saying...
So basically, if Manga say this release will fix the "dubtitle" problem, I'll get it. But since this is just a collection of past releases, I guess Naruto will still be off my interest radar.
