Get your wallets.
Well, I should probably elaborate further than just that. As we all know, the New Super Mario Bros franchise began on the Nintendo DS as one of the early titles. It was a reboot of the original Mario Bros with slicker graphics and new power-ups and levels. The first one was pretty good, but New Super Mario Bros on the Wii was where I felt the series hit the peak. While keeping the traditional Mario, yet bringing in new things, this game, the Wii Mario was awesome. Also, you can't go wrong with Mario Multiplayer, I just wonder if this new version will be different enough than the other ones. I hope you get multiplayer this time, but thankfully not on the same screen.
