According to Enterbrain, retailers moved 28,275 units of the PSP Go system during its first day of availability. While that's still a fairly sizable amount of hardware, Japanese gaming blog Andriasang points out that the DSi, which went on sale on Saturday, November 1 (2008), moved 170,770 units during its first two days on the market. We guess that just goes to show, if you want your handhelds to launch with a bang, launch them on Saturday. Also, put two cameras in them. Sounds silly, we know, but it works.
