That was said about a lot of games when ps3 and 360 hit the market and they went to ps2.
Uh what games? Only games that come to mind are fighters/arcade games, and even then, they got 360 ports at least.
Just saying, there is no obvious choices when dealing with japan. They don't act, rationally at times.
I'd like to think SNK does that mostly, but looking at some other titles, they were just trying odd money making.
