The Golden Collection clearly shows that Warner Bros. is treating at least Loony Tunes as much more than just a little kid's toy- it is VERY well done. I just want maybe a year by year release of all of the Loony Tunes. Disney would be wise to do something very similar, especially considering how well their cartoons have (or rather haven't) been doing.
The Batman animated series, in my eyes, is one of the greatest action shows to date, cartoon or not. Not only was it very accurate to the comics (much more accurate than any of the movies), it really captured the atmosphere and mood of Batman, and I really liked that. Besides, Mark Hamill does the greatest Joker ever.

I'd really also like them to release the Superman animated series on DVD, since I liked it almost as much as Batman.
