Both modes actually look very fun!
Oh and here is the boxart for when you purchase the game with the golden classic controller pro.

Here it is without the control so I guess there will be two separate box arts.

If you pre-order Goldeneye off Wal-Mart then you will get this Oddjob t-shirt.

Personally I think this is the best of the three deals because the codes will eventually be out on the internet while these Oddjob t-shirts will become a collectable item. I guess i'll be pre-ordering mine off Walmart.
