Don't think it'll convert the casual market. I think they would have bought one already had they given a damn. I know a lot of people with a Wii and they've not been used for ages and why would they buy another one?
Why don't they, once autumn/winter comes, splash out a ton of cash advertising the damned thing? By then, they'll be able to get away with promoting ZombiU, Nintendo Land, Pikmin, Game & Wario, Wonderful 101, Wii U Party, Wii Fit U, a new Mario Kart, a new Mario, Zelda Wind Waker, Lego City Undercover, Resident Evil Revelations, Monster Hunter 3, etc...
Most will be old news to current owners, but if you've not yet dipped in, that's not a bad list of games to be showing off, whether you're casual or other.
That leaves people like me. I really don't like the tech etc. on the Wii/U. The very fact it's nunchuck compatible turns me right off. So, it's going to have to be pretty damn special for me to want to get one. Wonderful 101 is the ONLY game on that list that looks any good. New Mario of any kind? Not seen it yet and I want to see evidence of games and how they look/play and not based on promises.
I know it seems like I'm bashing but it's just frustration and disappointment. Also autumn/winter will be when the new consoles from MS and Sony will be coming out. It's going to get buried under the hype these produce.
Nobody has got a clue what MS have got up their sleeve really in terms of interface. They'll be pushing Kinect 2 and probably Smartglass integration big time. It may be that they could convert some of the casuals to it. Doubtful but you never know.
Yes, I know Sony and MS will never have a Mario/Zelda/Metriod game but as of yet, neither has the Wii U.
Still, I'm hoping when these get released and they make the same kind of impact as the best Nintendo have done previously and get 10/10 everywhere.
The Resident Evil films. I'm one of the reasons they keep making them.
