As far as I know no, but there are rumors of them coming to the PSP and maybe PS3 sometime next year, though it's only a little known rumor.
I would love to see both of them remade for ds as iv was a brilliant remake.
No, sadly, Word of God says the "technical limitations" are stopping them from doing it (but since they did III and IV...), but they're considering 3DS remakes if the console does well. Which sucks, because i'd never trade my DS for a 3DS or buy one. ;;
