It won't happen. It didn't really rise when Wii Party was released last Summer in Japan. Wii Party is probably bigger than all of the games you mentioned combined...without Wii Play Motion of course.
I don't think these games will do much until the Holiday's. That is what the Wii does now. No matter how many games get released or how big they are...they don't do anything in Japan until the Holiday's. To explain, I expect Wii to sell around the same as it has been and maybe get a slight boost. During the Holiday's though the Wii will do better since these games were released now...its kind of like an after effect.
The Wii kind of does that in America and Europe too now except not to such a big effect. Wii is kind of officially the Holiday system.
