Floor plans for 2017 E3 have recently been on found on this website thanks to NeoGaf user Rösti. The floor plan shows Nintendo’s booth right next to the Sony booth in the West Hall. The approximate size of Nintendo’s booth is 32,000 square feet, similar to the size of last years Breath of the Wild booth. The NeoGaf post also says it is very likely that Nintendo has reserved the theater for some sort of presentation.
Will Nintendo go back to doing press conferences or are they sticking to Digital Presentations? Expect more details on this come May.
