I'd prefer the 1.0 method of every character having their own Adventure on the figure itself as opposed to a separate disc themed for the character. With Disney 1.0, we effectively got 29 Adventures, most of which were unique. With DI 2.0, we're getting 2 adventures, styled differently for Disney or Marvel characters, with no adventures on the figures at all.
Having the Adventures tied to the figures also males them worth the cost (let's face it, there are standalone video games that are cheaper than $15 at launch these days!)
I was originally excited to hear about the Toy Box Adventures, but seeing how few they released this cycle does not make me hopeful for 3.0 and beyond. My guess is that they will go the way of the goo next time around.
