Setting aside the morally neutral chromatic qualities of colours - including pink - their cultural associations vary through time and fashion, and across geographic regions. And of course different colours create certain psychological effects - agitating, calming, etc. - and in contrast to or harmony with other colours they advance and retreat and trick the eye. Pink may not be a major "guy" colour by present cultural standards but it has been macho in the past - there's an embroidered collar detail on an 18th century men's jacket that was on display in the ROM's Textile and Costume gallery until recently that's gorgeous, for instance.
Richard Beal, one of my ( straight ) design instructors at OCA(D) in the early '70s, and an avowed peacock, used to wear a pink suit to class occasionally ... and he looked splendid. He played against the cultural associations of that sissy colour ( strong in those days, even at an art school ) and it worked for him because it set him apart and created a certain mystique. I assume the marketers of X2 are up to something similar. They've certainly prompted interest here.
