It appears that more than 20 new Nintendo Switch SKU placeholders have been added to the database of retailer GameStop.

　　As spotted by eagle-eyed Nintendo journalist 'Sabi', about 21 Nintendo Switch Stock Keep Units (SKUs) have been added to the major retailer's internal database. According to 'Sabi', all of these placeholders are for unknown game titles and don't include consoles. With this year's E3 event kicking off next week, these listings might very well be related to new titles that Nintendo will be announcing.

　　Please note that these listings are just placeholders and we can only speculate about the yet to be announced titles that are coming to Nintendo's hybrid platform in the future.

　　E3 2019 kicks off next week on June 8 with EA's press briefing. Nintendo's E3 conference will be held on June 11 at 9 A.M. PT / 12 P.M. ET.
