With 6 to 7 million PS3's sold in Japan to 1 Million for the 360,

Let's go for the simplest answer to the question asked in the original post:

The Japanese install base of the 360 barely has any influence on games developed for Microsoft's console. It was like that in the past and it will remain that way until the end of the system's life. So whether the PS3 has a 3:1 advantage over the 360 in Japan, or a 6:1 advantage, or a 20:1 advantage, is irrelevant.

True, with an exception: development by smaller japanese studios who won't go through the localization efforts for the western market and could drop off the +20% costs of multiplatform development if that ratio really becomes more than 5:1.

As such, there might come into being a market of japanese-only second-tier JRPGs exclusive to the PS3, imported in the rest of the world.
