Probably not the full version of AE, but considering Adobe's dedication to amazing mobile apps, they might do something kinda like AE. For example, Photoshop Mix and Photoshop Fix aren't full versions of Photoshop, but they provide some of the functionality in mobile.
What aspects of AE would you like to see come across on mobile?
