I can't imagine him not taking GTAIV into account when he said that. And I'm certain he knew the production increase just announced was planned as well.
However, I ran my own numbers using weekly averages for the past 11 weeks (this averages out high and low weeks) and it comes up early July. This also doesn't factor in GTAIV or the increased supply. I'm guessing the GTAIV impact and the increased Wii supply will virtually cancel each other out meaning late June to early July is still the target period.
