The Nintendo DSi in its current form is just about to round its first Japanese birthday on coming November 1st, and if Nikkei has anything to say about it, the two-screener's all set for an oncoming growth spurt.

According to a report from the publication, who has a good track record on Nintendo reports thus far, a new DSi with 4-inch screens (versus 3.25 currently) is coming to the land of the rising sun sometime before this year's out.

No other spec differences, the report claims this was in response to older gamers having trouble seeing the action. It'll replace the current model and retail for the same price i.e. ¥18,900 (US $205.50).
