I never understood why so many people seemed so pessimistic after the E3 trailer...
It really seemed like a lot of people assumed the game wouldn't deliver because it isn't going to be Galaxy 3...
This new trailer seems to have reminded many of the general level of quality we can expect from Mario titles...
I was getting tired of the doom and gloom...

Because it looked painfully simple and uninspired.

I like it now. Whereas I was not interested at all at E3.

Looks good. Not extremely hype for the game but now at least it caught my interest.

Looks a lot better than the e3 trailer. Reminded me of a mix between Galaxy and 3D land, in comparison to the 3d land only we saw at e3.

i loved it, it looks so good now. i aim eating my words

I actually liked the E3 trailer but this one brings the hype to a whole new level =]

Do you think that there is a separate single player story or can you do the whole thing cooperatively?

Meh, it still basically looks like NSMB 3D to me. I'll get excited when Nintendo announces a true 3D Mario title that's on the level of Mario 64.
