Sony's PSPgo sells 28,000 units on first day in Japan, physical media points and laughs

Remember the "platform sales boost" that Sony was tauting after the PSPgo's release in the US? The question on everyone's minds was of course how much of that boost was buoyed by the new kid on the block, and while Sony still hasn't given us any domestic figures (nor will it ever, probably), we now know that the thing sold 28,000 units on its first day of availability on its home turf in Japan. That's certainly better than the measly 1,000 units moved in Australia over the same period, but hardly encouraging when you look at its predecessors. According to Media Create the original PSP sold 171,963 units in a day in Japan. The PSP-2000? 130,000. UMD may be hated by everyone, but it seems to still have legs.
