It says seller - Gamestop, available for pre-order from Gamestop. Somone more familiar with B&N can comment on whether this is normal for their website to list books they aren't actually selling.
Don't know if it's normal, but B&N used to own GameStop until ~5 years ago. B&N's major shareholder & founder [Riggio] had a lot of shares in GameStop, sold a chunk of them last year, and afaik still has some. All to support pure speculation that B&N may have some 'uncommon arrangement' with GameStop.
