Unfortunately I do have any of these, and have not viewed them to know the extent of the Special Features, but I am probably most angst to get my hands on the Tarzan CE... I saw a link to an auction yesterday, but it would have probably cost me 40+ dollars, and frankly I don't want to pay that. I am hoping that when Tarzan is rereleased which should be by 2005, since it has been vaulted for a few years now, or will be by then.
A Bugs Life, is a movie I haven't been that interested in, but since the SE has been rereleased for $20 it may be something to eventually check out, and maybe a second viewing will allow me to enjoy the film more than the first time.

Though the day before, or of, the rereleasing I got my hands on the original 2 Disc set (in the store) and looked at the SF included and it didn't seem to impressive, but maybe you just have to experience them...
Fantasia Anthology is something I was really trying to get my hands onto, until I saw the first Fantasia, and then my interest died away, but I figure with the 3 installment set for 2006, that the Platinum Edition of the first and Special Edition of the second, can't be too far off... I can definately wait on this one.
The Utimate Toy Box, is definately something I want to own, and do to the overwhelming amount of votes it recieved on the above poll, I'm guessing it's good! So this will definately be something to obtain I think.
Now I didn't vote, and don't think it would be fair to, unless I had actually all of these, and since I have seen none it would not be right to, but if I was voting on the one I wanted the most it would have to be
Tarzan...
