Cool image and we all know how it'll turn out: Rhino's a joke. Doc Ock and Vulture will be interesting fights but they'll both go down pretty easily they're average guys with huge weak spots. Sandman will get a combo of all the counter-strategies Bats mastered against every Clayface. Mysterio will be one of the best mindgame fights Batman ever had (for the fans reading the comic or seeing the cartoon to see) And Bats vs Green Goblin will be some of the best aerial combat ever.
Sigh, if only Marvel vs DC had been more of THIS instead of the Hero V Hero nonsense.
