I still don't really see it. The only sign of Takuya and Zoey that I remeraber was when Takuya had dream that he won a date with her after defeating Cheriubmon. Other than that, I didn't think that they were anything more than good frienRAB.
I was also disappointed that Sora and Tai didn't happen. There were a couple of moments during 02 that maybe hinted/showed Yamato and Sora, but the ending with them being married was pretty surprising nonetheless. As for the idea of the chosen children actually developing strong enough feelings to marry, I don't really think it's that much of a stretch. There are cases where people who know each other since childhood marry each other. Plus, we don't really know how their relationship led to marriage. For all we know, Yamato and Sora could have dated each other, broke up, dated other people for awhile, got back together and got married. It's still weird that Sora and Tai didn't marry instead, but with a twenty-five year gap, a lot of things could have happened.
That is certainly an awesome thought and I would love having all of the previous Digimon series on DVD. I'm not sure how likely it is for it the be uncut, but I'd be happy with either uncut or just the English dubs. That would be better than not having any of the previous series on DVD for me.
