[quote name='tossin']To clarify, it's a Metal Pak, a cheap Chinese knockoff of a steelbook. Still, it looks nice.[/QUOTE]
Actually if you go to the thread on the 360 CE that was on sale at Best Buy, someone linked the thread about the tin with the Dragon Age CE. The first print run of them were this MetalPak company's tins, but at some point in Dec. a second (and probably final) print run was done and it was changed to an actual SteelBook.
This is also why all the ME 2 CE's on 360/PC were Steelbooks. It's theorized that EA couldn't come to a deal with Steelbook before launch so they went with someone else, didn't like the quality (colors are much more bland vs. the Steelbook ones) and came to an arrangement with Steelbook.
Most people who got the Steelbook one ordered the CE in Dec. mainly from the EA Store, there may have been a couple from Amazon. Those who ordered at launch, like me, got stuck with the MetalPak one.
