What's wrong with japanese games or are you talking about the non localised ones?
The ports have more or less dried-up. it's mainly simultaneous releases with cross-play these days, something you will not see on Nintendo systems due to the difference in hardware.
It certainly hasn't been used to it's full potential, compared to the the PSP but I think Sony salvaged what they could from the situation.
The list was to show that games are still coming out especially since it has more than any other system for this quarter in Japan. I could have posted a list for the US for the year but this article was straight to the point.
I like my indie games which 99% are from western studios and I like my Japanese games too so for me, it's not just about Japan.
