In no way would they release them in Summer. Nintendo has started releasing its products almost simulatively, and if not, then with no big spaces. Nintendo Wii, the new console we'll have a global release in 2006. It will be just difference of days the time that it will release either in Japan or America and Europe. The reason that the Dungeons has such big space difference was because of the many texts to translatate, and mostly because of the official names' that hadn't been released. In my opinion Diamond and Pearl will mostly release in end of winter 2006 - start/middle of spring 2007. I know that sounds a bit weird, mostly because of the translation that sould be made, but it's 3-years developing game, there's neither time for apades, not is reason either. That's my opinion anyway.
