I hope that day never comes.I really hate the idea of video game steaming. Mostly because I am not just a gamer, but I am a collector. I love owning and having my games.
As well it would really suck to be playing a game one day, then have it remove because of some stupid reason.
I seriously doubt gaming will switch over to game streaming in a while, maybe in like 10-20 years, but for now, the next step is digital distribution.
Plus, with soulx's post, it seems most likely they'll do this for demo streaming or even using cloud streaming for other purposes outside of gaming. Like OnLive gives you a streamable desktop to work with. Not sure how this would apply to Sony, but it's just an example as to how streaming can be used outside of gaming.
Also I thought demo streaming (or something similar) has already been released?
