If Epic is successful in their lawsuit against Apple, then I think it's only a matter of time before the consoles will have to allow alternate stores as well.
The hardware-is-sold-at-a-loss argument that people like to use to defend closed console stores isn't as convincing when the console makers also own the biggest money making game studios as well.
Kind of ironic how bad an argument that is when discussing anti-trust. It's a form of dumping to distort the market. It prevents new competitors becoming viable purely by selling hardware.
Following from alternate stores on consoles, we're not far away from Valve's SteamBox, i.e. prebuilt PCs marketed for living room play. I'm disappointed the idea never took off.
I would love the game industry to fully embrace Linux. If cloud gaming gains more traction, the industry might just do that. Why develop games to run on custom-built blades in a data center when generic blades exist?
