I would check EBGames or Gamestop, if you have either one near you. They usually have much better information about release dates than Toys R Us does. If you pre-order there (at least at EBGames) and then decide to buy elsewhere you can cancel - usually you only have to put $5.00 down and you can get that back if you cancel.
Last I heard, the Pink bundle has been delayed to come out a little closer to Christmas. The Teal bundle should be out this week. There will also be a red bundle that comes with MarioKart - it hits stores Nov. 28.
(By the way, for anyone getting a DS, I highly recommend Animal Crossing:Wild World, which ships Dec. 5.)
