Japanese sales.... I can see why developers get a little gun shy

Ok, let me restate everything

Attachment ratio is very important if hardware developers want to attract software developers. People who make games want them to have the best chance of selling as possible.

So, with that in mind, let's look at the japanese attachment rate for 3 of the big consoles (psp, ps3, wii):

for the psp, the console has been on the market for three years. It came out right around the same time at the ds. Yet the ds attachment rate is 4.5/1 in japan and the psp is something like 1.7/1.
How do you convince a japanese based company to release a game for your system when the sales are so low in japan? Once again, it's been 3 years, it's not like the system just hit the market. My point being that it's a very unstable market for japan based developers.

For the wii, the nintendo sells about 2x as many consoles in US as in japan. But, most weeks (unlike the first week brawl was released), the US sees 4x the software sales.

ALL I'M SAYING, is it's a crappy time to be a japanese based software developer (the isn't nintendo).
