Mario all stars 2009!!

My guess is either a DS re-release or a NSMB-style graphical (and maybe gameplay?) update, plus the addition of a demo of NSMB.

 

I'm going to lean toward the theory that Nintendo is re-releasing the original Super Mario All-Stars, but upgraded yet again with New Super Mario Bros. graphics (and maybe some gameplay/control upgrades as well). I believe they'll release it for the DS and for the Wii both. The DS version will contain a demo of New Super Mario Bros, while the Wii version will have a New Super Mario Bros. Wii demo.
