The main upgrade is of course the 4.2 inch screen, up from 3.25 (resolution unchanged).

Battery life increases to 3 hours again, but weight goes from 214g to 314g, and the unit fattens to 16.1cm by 9.14cm from 13.7cm by 7.49cm. Otherwise the unit is essentially unchanged from the DSi.

The price is in the region of ¥20,000.
