Making your own Mario stages...

Coming sometime this year is a new Super Mario game called Mario Maker, where you can make your own stages. So far, it looks like you can make them look like Classic, Super Mario Bros. 3, Super Mario World, or Super Mario Bros. Wii U stages. While this is "Super Cool" (did you catch what I did just there?) I am hoping that you can also make your own Super Mario Advance 3 World E stages, since I've never been able to play Super Mario Advance 3's World E stages. Of course that's just my option, what about you?
