I'm not going to validate the idea that you can change the true character of something simply by putting artificial restrictions on its use. So I don't really agree with your thinking on this. The way I see it, something is a video game console is it primarily exists to play video games. The level or quantity of anti-features present in the device is irrelevant. So either Xbox 360, PS3, Wii, SteamBox etc. are all "gaming PCs", or they are all "video game consoles", or they are both.
