Wireless / Networking
WiFi on E3
Knowing the WiiU loses connection easily with its 5G wifi, how does the wifi on PS4 relate on a crowded environment? :

"Always On" feature
There seem to be no requirement for a continious internet connection (ofcourse unless you want to use services that require them, like PSN/SEN, online mediaservices, share button etc.).
Same requirements as WiiU - while in the Xbox field there was some discussion about the need of it. See also : http://games.yahoo.com/blogs/plugged-in/microsoft-exec-stirs-controversy-always-xbox-twitter-tirade-173337715.html
