We found out last week that Capcom had some GBA Wii U Virtual Console games planned for release. Although it was quickly identified that said titles would be Mega Man Battle Network 3: Blue Version and Mega Man Battle Network 3: White Version, it would not appear that the Big C has even more penned for an eShop release.
In reference to this, Capcom said the following:
We are working on bringing this and other GBA titles to the North American Virtual Console. We’ll have more information about the lineup in the coming months. For Australia and Europe, we are still in discussions about the release of Virtual Console titles for those markets.
And there you have it. Let wild speculation begin. We’re personally hoping for Onimusha Tactics and Mega Man Zero.
