Don't get me wrong, I am totally looking forward to New Super Mario Bros. as well, if not more. However, I think that it is more properly suited to sprites, not polygons. Nintendo have always had a great ability to create detailed and original looking sprites. With all the polygonal games that became the norm with the N64 in 1996, we see that less and less. I just think it would be cool for a game that is reminiscent of the classics in gameplay to have a graphical style that is, too.
