I voted for Donald. I hope all of his shorts with Chip and Dale will be included. Those are my favorites.
I'm also looking forward to Zorro too, thought I guess I'm the only one. I used to watch Zorro all the time when The Disney Channel had it on. It was on at midnight for me so it would be the last thing I'd watch before going to sleep. I only hope they do not colorize them. That would make me cry.
I would actually like to see some sort of Winnie the Pooh collection. It probably wouldn't be a Treasures set, but it could include all post-Many Adventures shows. It could have Day for Eeyore, as well as all the New Adventures, and the DTV spin-offs from it (Frankenpooh, A Valentine for You, And Christmas Too etc). They'd also include House at Pooh Corner, and Book of Pooh. It'd be a large set and somewhat repetitive, but there's a lot of Pooh fans out there who I'm sure would pick it up.
