In smaller countries with fast internet connections, and no data caps, available to everyone, I assume cloud gaming will become a big thing within the next 5 years, if not sooner. However, in North America and Australia, where low data caps and slow speeds are the norm, and servers can be quite far from some people (midwest, Canada/AUS in general), it's going to take a lot longer. For those gamers who really want the best experience possible, a physical console is always going to be the best option.
