Reconfirmed: Virtual Console, WiiWare games can be transferred to Wii U

No need to re-buy anything.

A few months ago, Nintendo confirmed that gamers would be able to transfer Virtual Console and WiiWare games from the Wii to the Wii U. The latest issue of Game Informer has confirmed that this is true. I thought this was common knowledge by now but judging from the comments I've seen on other sites, there is a large percentage of people who still don't know about this. Either way, this is good news for future buyers of Nintendo's new console.
