I wonder how these people feel about other media. I'm not a full-time reviewer, but I am a published one. I have gotten many a free CD or book for review purposes. This is not considered a bribe in either field, and CDs and books are far less expensive.
Further, my father IS a full-time reviewer. He even gets unsolicited material. Also not considered a bribe. And he's actually gotten stuff with is name on it before. The reason for the PS4s having the reviewer's name engraved on it seemed obvious to me: this would prevent resale of these desirable devices or allow the seller to be identified.
Some music groups have gone so far as to send out review discs glued into portable CD players designed to be returned. Entertainment media does not want the reviewer to keep, or worse, distribute, the media they're reviewing. If Sony can 'damage control' use of such consoles, they will. I bet they'd go further if they could feasibly get away with it.
I almost feel bad for games reviewers if this is to be the standard. Douchey or not, posting pics with review material does not merit a desire by the gaming community for one to have to bring their own media.
Also, Jim, please tell me you're going to action that PS4 you licked for charity or something. >.>
