In case you didn't know or have been living in a cold war re-enactment zone, Wii will soon have some new content along with some awesome games come May of this year (2008). From the looks and rumors of it, it won't just be old ports to the new system or anything. Pricing has not been set as of yet.
The site that is up is only in Japanese, if you follow the link Google will translate for you. Here is a short list of what looks like will be coming out soon. Of course if you have access to the Japanese server for these downloads, you should be able to get them within the month.
