if i were to get a switch it would be a year late to verify that nintendo actually plans to support the device long terms with games i want. their promises aren't worth a nickel to me..
...so i'd get zelda. mk and smash would be a maybe. if a actual sequel was annonced by then i would skip the ports and just get the new version. these games are ussually a once in a generation game so i wonder if nintendo will even make a sequel for them or just offer up these ports. i think sakurai said he doesn't want to make any more smash games a while back.
