Earlier today Natsume made the announcement on their Facebook page about the upcoming game coming to both the DS and the 3DS. It is quite possible that this is a US release for the Harvest Moon: Twin Villages DS game that came out in Japan last Summer. Natsume gave no other news about what is different between the 3DS and DS versions but did say they would have "exciting news" about the games at E3. Source. I for one am excited about this. From what I've heard Twin Villages is in the same style as Grand Bazaar featuring a rivalry between two mayors and their villages as well as adding in a few new animals to take care of. I wonder what's up with the DS/3DS versions though, it's an interesting move to make. It reminds me of the whole GC/Wii Twilight Princess thing.
