I am not even convinced to buy the Wii U right now. Sure, the Virtual Console Trials are nice but the thing is, I already have all of those games on my Wii and/or 3DS. Now, if the American Wii U owners were getting Fire Emblem: Mystery of the Emblem AND EarthBound like the Japanese Wii U owners are getting, I would be convinced to buy the Wii U. Also, if they actually showed some GBA games which would be the first games available on the Wii U such as Advance Wars, Golden Sun, and Legendary Starfy (for all the regions, not just Japan), I would be convinced to get the Wii U.
So, for now, only E3 2013 with trailers of new Mario 3D game, new Mario Kart game, SSB4, Wind Waker HD, and Yarn Yoshi will have to work their magic to convince me.
