Shame it's unlikely that there will be a portable equivalent. Would love to have Dreamland 2/3 and 64 on my 3DS as well.
Dreamland is already on the VIrtual Console and Dream Land 2 is on it in every region but North America. We'll probably be getting it soon though.
Obviously the others won't be coming though.
