Not really. I mean, sure, to the customer that's about it, but to really change the stores over they have to migrate the inventory infrastructure, all of the vendor relationships and communications types, distribution and data warehousing, etc all over to the existing Gamestop system whereever their corporate headquarters happens to be. It's a really big project that takes time. This is some of the stuff I work on for my employer.
Of course, having seen some of Gamestop's backend technology, let's just say there isn't a ton of point to moving anything into it. It's laughably bad and if you know what you're looking for it is directly manifested in their stores and their performance.
