I couldn't help myself, I smiled at the people who responded that they saw it in my review! You actually watch my stuff! 
Sorry, back on topic: I actually think the SM3DW graphics engine always had this capability, but that it was scaled back a bit to consider 4-player mayhem. Nonetheless, I have to agree that it's good to see that Nintendo recognized the extra room and decided to make use of it!
