Just as a suggestion I think that play station network should combine with xbox live. And then playstation could charge it's users just like xbox does to bring in that extra cash. Then playstation owners can play with their friends who own an xbox and vise versa. I don't know how easy this would be to do but this would be a nice addition in the playstation 4.
