I'm happy to have this rather than nothing, and I might buy them, but I certainly wouldn't be if I already owned the original DVDs.
However, while I don't know what anamorphic technically means either, I get the impression these are going to be full-screen, fuzzy, generally crappy quality copies, and that's just not right when everybody knows that they could've at least given us crappy-quality widescreen versions. But I think what everybody was hoping to see was a remastered version of the original movies, in almost as good quality as the new versions. That's not really a whole lot to be asking for at this point either, but instead Lucasfilm wants to take the cheap route and still see if they can squeeze money out of the fans. It's VOTC C3PO all over again, so to speak.
Frankly, if Lucasfilm's position is "oh noes it's expensive to remaster the whole movie again," then surely they have some unedited copies from when they were working on the '97 SE, but also, if nothing else they could splice in the scenes that weren't edited/weren't edited significantly (sound modifications, stuff like Piett's rank badge) and only remaster the scenes that were truly modified (Han and Greedo's original exchange and such).
But, as I said, I'll buy these if nothing better comes along and I don't happen to find the original DVDs a lot cheaper. But I sure wouldn't be buying them if I had the original DVDs, because these copies are nothing to get worked up over- you could easily do the same thing yourself and apparently it'd even be quasi-legal.
