Wow. Thanks for the list.

You're welcome! I'm not sure why it pasted strangely and the dates scooted up next to the title (I copied from my Facebook file on my local Wii U Owners page), but I'll try and fix that later. Pressing "tab" doesn't work.

Thanks alot. You make me feel a ton more comfortable, knowing we have alot to look forward to.
P.S. I believe you forgot Skylanders Swap Force.

Bayonneta 2 will be coming this year?

Also i thought wind waker hd was going to be released in September ,but what do i know

You're right, Bayonetta 2 should be TBA. Development is going well, but that doesn't mean '13 is guaranteed.
The Wind Waker seems to have conflicting rumors between Aug and Sept, but it seems a Q3 release is the word from IGN a la Nintendo.

Added. and we do have a lot to look forward, even if it's pouring in slower than hoped. A year from now, we'll be very satisfied Wii U owners. Hopefully we'll get even more announcements (or at least release dates) before E3.

As for Call of Duty, I presume Modern Warfare 4 in November is a safe bet. Assuming the Wii U gets a CoD game this time. This game is made by Infinity Ward and IW have NEVER made a CoD game for a Nintendo console. So it would be a first if they did.

2013 and 2014 would be expensive.

There's at least 2-3 games I want each quarter, which will probably last me a month each.

Mmm yes. This pleases me.

This list makes me more confident in the future of Wii U but also makes me uncomfortable thinking about the how much this will cost. O_O

Aaaaaand... I'm broke.

It's okay. I didn't need money. Really. >>

I'm obviously not buying all of them, but damn, there's got to be at least five big games there I want to buy, and I don't even have a Wii U yet. This year will be painful financially...

Thanks for the list. Pretty dissapointing, as Lego City is the only game I'm really looking forward to in the next couple of months. And it's single player only, sadly.

Y U make lineup so comprehensive?!?

The only way I found to do it, on another list, was using underscores.

Great list. Is Fez announced, though?

Saber Rider and the Star Sheriffs has my interest. I'm a sucker for most 80's cartoons. XD
