I worked with Mark Cerny (who presented yesterday) on Crash Bandicoot, and even by HN luminary standards he is a god-like superhero. Given that he's evidently played a key role in developing the PS4, I seriously doubt anyone will be disappointed when they see the physical machine. Sony probably just didn't want to leak details that could help competitors.

They announced the complete system specs(http://www.polygon.com/2013/2/20/4009940/playstation-4-tech-... ) That's more than enough to "help" competitors.

The console manufacturers don't have any reason to copy each others aesthetics, because confusing branding doesn't help any of them, and there's no functional reason for them to all have the same shape/form factor.
