Yeah, 1 made. It went for 1000s on ebay unfortunately I was not there to bid! :'( They are embossed, and it comes with matching controllers seen in this photo. It also came with a bunch of other free stuff. IDK why they didn't make more of these...C'mon!
There will almost certainly be a bundle (no source, they just seem to do this with most big games nowadays) but a unique actual PS3 I highly doubt. There may be one but produced in very little numbers like the Darksiders PS3 and GTA Episodes from liberty city PS3 (just remembered that 1) so we won't get our hands on 1 anyways
