The Wii Blues

More of a rant than anything, I'm curious as to why there are two future DS titles prepared for after Sunshine Islands, and yet no speak of a Wii release.  Harvest Moon: Welcome to the Wind Bazaar is the next title coming to the DS, followed by Harvest Moon: Twin Villages.  

Wind Bazaar: Welcome to the Wind Bazaar is the next title to be released for the DS.  Very promising, it introduced the opportunity to sell items to other villagers at a weekly Bazaar.  You can also purchase items from other villager's booths, and more will open as you advance in the game.  Another feature is the ability to connect and play at another friend's village via Wifi connection, and up to four people can participate. Not much is known about the game or release date yet, but more information should be available soon.

Twin Villages: Twin Villages puts a new spin on the HM series by, for the first time, allowing you to choose the town you'll live in.  One is centered around farming, the other ranching, and the choice you make at the beginning of the game will therefore affect how the rest plays out.  My understanding is that the bachelors/eligible girls and villagers are different based on the town you choose, but this could be misleading information.  Twin Villages also introduces the ability to raise alpacas and, wait for it...bees!  As the release date isn't yet set for even Japan, it's hard to determine when the US release will be.

And seeing how unique and promising these games sound, I'm shocked I haven't heard anything about another Wii Harvest Moon yet, not even plans!  My initial thought was that Nintendo would be introducing a new console and, therefore, the next HM would be released on that.  Nintendo is introducing a new console, but known as the Wii HD with high-def features, which should not affect gameplay now.  This brings me to the conclusion that there is no information on a follow-up, which is hard to swallow.  

I assume it would take a long while to design a Wii game.  I doubt that if Natsume is creating another HM Wii (which they'd better be!), they would recycle the same basic characters yet again.  This leads me to believe that the concept and completely new design would be causing the stall, but what do you think?
