Interesting interview with Capcom about a 'chance' of seeing this.
Ducktales Remastered is SCREAMING to be featured on a portable unit. One 'possibility' is that it might have a chance to see itself on the Nintendo 3DS. Here is an excerpt of an interview with Capcom that talked a bit about this.
PNM: I’d love to play a port of DuckTales on the 3DS. Is there any chance of a port?
There’s always a chance for anything, but we’re only talking about the console and PC versions at this time.
Whether it be for the PS Vita or the Nintendo 3DS, I personally feel that bringing back old school hits, remastering or giving them the "HD" boost ala Wind Waker, would benefit Sony or Nintendo with their portable units. We will keep you updated on this but check out the interview here.
