I was already planning to buy a Wii U, but after today's announcements, there's no doubt I will be. It's $350 for the premium version (two versions you can buy), which is really cheap given that it's a next gen console.
So many great looking games for it, from awesome exclusives like Pikmen 3 and ZombiU, to all third party support such as the Batman games, Mass Effect games, etc (thus tons of future support from these development teams). However, the big thing is, Bayonetta 2 was just announced as an EXCLUSIVE to the Wii U. That's a huge game with a huge following, and it's now an exclusive Wii U series. Plus, Call of Duty: Black Ops 2 announced for it as well.
Things like this shows Nintendo is very serious about capturing "hardcore" gamers with all sorts of awesome exclusives of serous games.
The system launches November 18th in America.
