It's got to be a pre-order bonus, surely.
Their first reveal was, "Sometimes it's nice to treat yourself, but it's even better when we do it FOR you. Stay tuned-- we have a surprise coming up that you won't want to miss."'- This says to me that they'll "give" us something extra for pre-ordering.
One thing I would like to see though, and I would be suprised if they do, is the inclusion of all things Infinity in the Disney Movie Rewards scheme. That would be totally awesome as I have just under 3000 points sitting there doing nothing.
