Lauren (Tor-chic if your a Pokebeach fan) has just informed me that she has found out what the Toys R Us reserve bonus for Black and White is going to be. Apparently, instead of getting cool figures like with Platinum, Heartgold, and SoulSilver... we will be getting Zekrom and Reshiram window clings. Whoo hoo.
It's unclear if this bonus will be just at TRU or if it's going to be the bonus that is also given away at places like Wal-mart and Gamestop, however it is highly likely. Like Lauren said, "TRU and Gamestop have given out the same reserve bonuses with the last 3 games. Both gave out the Dialga/Palkia stylus with D/P, Giratina figures with Platinum, and the Ho-oh/Lugia figures with HG/SS."
For Heartgold and Soulsilver TRU gave away, in addtion to the Lugia and Ho-oh figures, DS kits which had a Lugia and Ho-oh screen wipe as well as Gold and Silver DS cartridge holders and tshirts, so it's possible that the window clings are not the only bonus for reserving at TRU. I'll post pictures when we get 'em.
