I see that 
Stitch! is now available for pre-order. I added it to my wishlist. I found a better list of of the "bonus features" at another site, including these items:
- Stitch starts it off with animated menu fun
- Trivia challenge!
- See the evil Dr. Hamsterviel's production of "The Making of Stitch!"
- Experiment finder - help Lilo and Stitch find the infernal experiments
- Experiment gallery - meet more aliens and discover their powers
I know two little boys that will be really excited.
