Those OVA discs you see are a North American re-release of OVA 1 and OVA 2.
The reasoning behind this is that since the first two OVAs are only available on DVD in a box set form, which usually sells for anywhere from 100-130 dollars, these DVDs that are being released might be easier for someone to buy one at a time instead of having to splooge on the whole set.
Also, if you have the Tenchi box set like me, you probably know that the episodes are not split up into chapters.. each episode is a chapter, rather than being split up by opening, part a, part b, ending. I think the new discs will be split up like that.
Also, for the true Tenchi fan, these discs will be a good thing to buy even if you already own the DVD box set. As a collector, you'll want them anyway. As a viewer, you'll like that the video on these discs will be MPEG-2 instead of MPEG-1 which was used on the box set so they could fit all 13 episodes on 2 discs.
And then of course, we are all hoping for maybe some new special features... textless opening and ending... etc... And maybe, just maybe.. a new version of the Tenchi Encyclopedia! That would be awesome!
Furthermore, you have to think.. with OVA 3 coming out, Pioneer will probably want to, at first, release OVA 3 on a pair of (Or maybe even 3) discs, since it's rumored that OVA 3 will be 6 episoeds. So, releasing the first two OVAs is kind of liek a precursor to the release of OVA 3.. it also suggests to us that, even though Funimation (probably...) has the rights to GXP, that Pioneer is not giving up their rights to the Tenchi OVA.
Finally, and I am hoping for this wholeheartedly... after everything is out in America, maybe they'll make a new box set with the complete trilogy. That would kick major ass

Of cours,e then again, that depends on the news from Japan... Appearently, if OVA 3 does well, Kajishima wants to make OVA 4. He's hinted at it a couple times, and so have his staff people.
Most fans think that OVA 3 will be more action oriented, as it focuses on the Choushin war, and then OVA 4 will end up being like the beginning of OVA 2, with character developing episodes, as well as maybe some romantic aspects (Since the AIC staff have jokingly said, in response to people asking if Tenchi will choose a girl, they said "Maybe in OVA 4")
And then of course, in OVA 4, we can look forward to some GXP cameos since OVA 3 is pre-GXP, but OVA 4 will be post GXP.

Hehe! Maybe we'll get to see...

Anyway, time will tell. They've been keeping a tight lid on OVA 3, but since we now know who the staff is, hopefully we'll get some word on what it will be like plotwise.
