That is a bit of an exaggeration. My Intense M-1 from 2000 (18 years ago) had 8" rear travel and between 180 and 190mm front travel (I swapped forks a few times). Head angles have slackened out a lot (and I had my M-1 set as low and slack as possible), but the big change has been in the center-front and overall wheelbase of new bikes compared to older DH bikes. Those old bikes look tiny by today's standards.
And the 2018 Nomad "4" has 170mm travel, front and rear, not 160 - that was the old 2017 "3" version. Reviews I've seen so far say the Nomad 4 climbs surprisingly well. It won't be mistaken for a XC bike, but it "hides" the amount of travel well when pointed up.
