Best Buy Canada’s E3 promotion page has placed three other covers next to the Splatoon 2 and Mario Kart 8 Deluxe. The covers, each listed as “To be revealed at E3”, will supposedly be available for preorder at Best Buy soon.
While it is easy to speculate what three games may take the place of the placeholders, it is also strikingly odd for Mario Kart 8 Deluxe to be under the pre-order category having been released back in April. For all we know, the placeholders covers may be a mistake or just there to fill in the gap.
