That doesnt confirm 100m sell through, he said over 30m in US and around 30% of total sales. It could be 30.1m in US and be 30.5% of sales which would be like ~98.7m globally.
Since he didn't specifically mention 100m sell through and Sony hasnt commented on it yet than it's safe to say it's not quite there yet.
Sony not announcing 100m as soon as it happens doesn't confirm it hasn't reach it either. The same argument has been made in the past, sure not for as big a milestone, but people claiming sales must be lower than a certain figure because lack of an announcement only to proved wrong later.
Zhuugex likely hasn't mentioned it because he's not completely sure, after all he says "over 30m", "approximately 30%" and as you say, without EXACT figures you can't say definitively one way or another if it has passed 100m, so he doesn't.
Personally as of today I'm sure the PS4 has sold-through over 100m, but we'll find out soon enough.
