Back in early December we reported a 256 MB Memory Unit being listed on Gamestop. Apparently, the same page now lists the card as being 512 MB, double the capacity of the previously unconfirmed accessory. This definitely can support the rumors of the new 250 MB cap for arcade titles and even the 450 MB limit that needs Microsoft's approval. The $49.99 price tag isn't that bad, for those that utterly oppose buying a hard drive for their 360. With the 20 GB alternative out of the equation, ten bucks for eight times the storage is an obvious steal. So would you pick one up if your 360 is a Core, or your profile is on the go between Xboxes?
