Like people already stated, integrated platform with all big Nintendo IPs on one platform, great concept that aims at handheld and home console owners at same time, some big 3rd party games in full handheld mode, multiply revisions, Nintendo said they want longer life span than usual 5-6 years....It's still hard to tell but definitely has good chances to do 100m+ at end, I mean Switch will end 2018. year with 30m+ (thats less than 2 years on market), so minimum that Switch will sell at end is 70-80m, so I wouldn't bet against 100m+.
