This week’s hardware chart shows that console sales in Japan had a slow week during January 14 to 20, with a noticeable drop from the week prior. The PlayStation 3 dropped the least, holding on to respectable if headline-avoiding sales. Amid no new releases for the past few weeks, we shouldn’t be surprised. And we aren’t. We’re just a little impressed at the PSP’s ability to hang tight with casual gamer darling the Wii.
