The latest email confirms that GameStop is indeed working on a competing service with its acquisition of Spawn Labs, and that because of an "agreement" with Square Enix, all of the game's copies will be recalled back to the publisher. The one exception is reserved copies, which will still be available for purchase, according to the memo.
GameStop has also pulled the PC version of the game from its website, though the console versions are still for sale. Joystiq has confirmed with local stores that the memo was received and copies were being pulled. We're also contacting GameStop corporate for an official statement on the matter.
