I hate to say this, but technically, fallout 3 had separate pieces (hat, armor, eyewear). I guess its still possible that we might have separated armor, but it will be less chopped up than in TESIV. Maybe we will get "armor" (shirt and graeves), helmet, and boots.
You could say that, but the question the guy asked on the right was 'Will Skyrim's armour be one piece or separated into cuirass, gauntlets etc..' which kind of suggests he means that it will be like Oblivion, but there is still a (somewhat slim) possibility he could just be talking in crafty company jargon that means it will be 'hat, armour eyewear' as you say. But mainly I think he means like Oblivion.
Originally I though this post was about whether the pieces would be comprised of pauldrons, right gauntlet etc. but it actually tells us nothing about that except that its not like Fallout's one-piece armours...
