Starting immediately, Nintendo is releasing several of the most classic of original Wii games to the Wii U. They'll be doing this with full-sized releases of said games, starting with Super Mario Galaxy 2 - available right this minute. Starting on the 22nd of January you'll be able to roll with "Punch-Out!!", then on the 29th of January you'll find the Metroid Prime Trilogy hitting the Wii U in original Wii format. At this time it's not entirely clear how high-quality the delivery of these games will be - hopefully ready for slightly larger screens than the original Wii was prepped for.
