I went to Toys R Us two weeks ago to wait overnight for a few Wii. They had this bundle too (although back then, it came with a controller glove too).
But as everyone else was saying, Toys R Us can't force you to buy a bundle. They recently got into trouble for that.
Also, my store had divided their allotment of systems. They told us that half were bundles, and the other half were system only. Maybe your store will do that, maybe not. Even if they say its all bundles, that still has no effect on the fact that they can't force the bundle on you. They just aren't going to tell anyone that.
