no, but the level of fidelity needed in the internet connection and then the hardware on your home end to make say the 4k option worth while (the option that is actually better than a console) is going to be a combination of clearly has a bunch of spending power, is interested in gaming but doesn't have their own hardware already.
which doesn't feel like it's going to be a lot of people.
Because this is not movie streaming, you have to be able to interact with this in real time which is going to need really good ping times to not feel like trying to control the game through some one else.
which are basically the same problems Online and Gaikai had when doing this 10 years ago.
