Personally I usually think it's stupid to remake games that are just a year old, or even from the previous generation unless there is some justification, but I welcome remakes and ports of ('deserving') games that are older than the previous gen. So, if they're going to bring true remakes of GC/GBA games and older to 3DS, I'm all for it.
@ Iwata, I wonder how he plans to boost profits to a whopping $800m starting next year...
EDIT: I'm calling Super Mario Sunshine 3D by the way.
