Will there even be "blockbuster" video games, movies, books, etc? If hours after release, there are hundreds of lookalike clones, will there be "hits" like we know of today? We see this in the App Store today. It is just hard for me to see that part-time product being a big success, when at the first whiff of an interesting idea it will get repackaged, probably into something more effective.
