I came across it as I checked to see today's Virtual Console releases (Kid Icarus, Kirby Adventure, and Ice Climber fans should be pleased) and share it because it is short and to the point:

DID YOU KNOW? NINTENDO'S SUPER PAPER MARIO IS HEADED FOR WII

Nintendo of America Requests the Pleasure of Your Company at the Marriage of

Peach
to
Bowser

on the 9th Day of April 2007

The nuptials will take place at the beginning of Super Paper Mario™, which will be available for Nintendo's hot new Wii™ home video game system. Those who wish to attend - or thwart - the ceremony will need to switch between 2-D and 3-D.

Seems to have caused a bit of chaos on some sites - one site (not sure which) misinterpreted it as meaning it would be a VC download and that seemed to spread.

Oooh! I just might finish Hotel Dusk in time! ^_~

Easter Monday, eh?  Maybe I should take a little spring break off of work...

I want this game SO BAD. IGN has some vids up that really cemented the purchase for me:

Another Gamecube loss is Wii's gain...I wonder why they even bothered with a GC announcement.

f--- you too Nintendo...And have a nice day when I buy your system and this game for it anyway. I guess that's a fair deal (even if my GC doesn't think so).

They've got an official thread going on at the NeoGAF forums.  Nicely done:
