What was Nintendo's golden decade?

We have yet to see the truly new Mario game for the Wii U, but Yoshiaki Koizumi says it is coming. The REAL Mario game for the Wii U will amaze you, trust me.

New Super Mario Bros. U already amazes me, though compared to NSMB2's mediocrity, it's not hard to pull off. I see a lot of replay value in U; Challenge Mode is something brand new to the series and Boost Rush is an improved Coin Rush, Coin Rush being close to useless when the 9.999.999 coins milestone is achieved, part due to a terrible highscore system.
Nabbit is a huge step forward from saving Toads in Wii, which is a total waste of time knowing Green Toad Houses exist. Heck, even the story is different for a change.
NSMBU may not be spectacular, but it amazes, especially compared to the earlier NSMB titles.
