Oh come on, no console - including the 360 - has ever been like that. There has never been an anti-virus, much less one that prompts you at startup. Console software updates are few and far between (twice a year on MS's schedule), not to mention it looks like they're doing more and more in the background.
Nor has Microsoft or Sony ever held up anything so you can watch a special offer. This is just FUD.
Go watch the keynote, they cover all of this. They're betting on voice control lowering the "depth" of the UI. Instead of "TV -> live TV -> Sy Fy -> Star Trek" it's just "go watch Star Trek", ditto for on-demand, ditto for sports, ditto for games even. Everything they showed today indicates single-action-to-final-destination.
