And yes there is 5 episodes (plus prologue/epilogue). The epilogue won't have sly's dad because artwork showed an exploded blimp so I think it's a short 1 mission outro to the game involving a final boss fight.
 * sigh* altitude sickness (the level Bentley did a presentation) is the last job in that episode. They could have more slides between depending on if they removed them to save time.
