I predict sexbots with interchangeable parts.
I predict sex-bots that have the likeness of real world people. Either licensed/sanctioned, or bootleg. There might be copyright issues with your appearance or likeness. Famous people might have to produce sex-bots of themselves, whether for sale or not to simply to establish copyright on themselves. People might start scrubbing social media for photos and audio/video of their intended target and have some place make a custom copy.
I further predict non human sex-bots, fantasy creatures, and replica real-world animals, and then a thorny legal issue of sex-bots depicting underage people.
Oh, and all the same for virtual reality, which might actually come faster, or negate the need for a physical bot altogether should the haptic feedback technology or direct neural stimulation improve.
