Flash developers usually get a fixed chunk of space to work with and any trick they can use to squeeze 'more UI' out of that same space will be used. If hovering is no longer an option you can expect the size of these blocks to increase to offset the extra real estate required to accommodate all the bits and pieces of the UI. What is more likely is that the user agent will be detected and that if it is determined that the user has no mouse that either some fall back mode will be used or that there will be an alternative UI preserving the basics will be presented, or a UI that will use the first 'tap' on the screen as a substitute for a hover.
