Sure, I might already have the Toy Story and Toy Story 2 DVDs. Yeah, I can find the majority of the featurettes from almost any Blu-ray online. Nevertheless, I have already pre-ordered the 10-disc Toy Story trilogy Blu-ray+DVD combo pack. And I recommend you do the same.
It just went up for pre-order on Amazon.com at $69.99, with a list price of $100. Not much is known about the set yet, but I'm sure it will be jam-packed with all kinds of great featurettes that cater to the tastes of folks just like you and me--folks who love Pixar.
The set will be released on the same day as Toy Story 3, November 2 this year.
