Yes, yes and Hell yes.
I always try not to get too hyped for E3, but it never works out.
And this year is going to be excitement overload. The combo of playing MK8 + Nintendo's E3 goodness is gonna be awesome.
Not really thought about predictions. It's pointless anyway, Nintendo simply can't be predicted.
I will say this though, with Mario, Pikmin and DK already out, plus MK and Smash pretty much done and dusted, it means mucho surprises must be heading our way.
