Kotaku's Luke Plunkett:
Home should not be shown at trade shows. Absolutely not. Not under any circumstances. Why? Because it is boring. Home is not a game. It's not even a user interface. It's a...thing. Once Sony get around to deciding what that actually is will probably be the time they decide to release it, but until then - and especially in the state it was in for my TGS demonstration - it should be kept as far from prying eyes (and hands) as possible.
