Nintendo are tipped to be readying a refresh to their DSi handheld, timed to coincide with the games console's first birthday on November 1st. According to Nikkei, Nintendo Japan are readying a new DSi with dual 4-inch displays, rather than the existing 3.25-inch panels used in the current model.
Update: A Nintendo spokesperson has told Famitsu.com that "Our company isn't doing any interviews [about this]. We think it's a speculative article." Neat sidestep, guys.
