Andrew House, Sony Computer Entertainment president and CEO, spoke with The Wall Street Journal at GDC 2014 about keeping up with PS4 demand during a post-release period when interest in the console remains high. "We're struggling to keep up with demand," said House. "Conservatively, as we get into the early summer months, we'll be closer to a full supply situation."
As of the first week of March, Sony had sold 6 million PlayStation 4s worldwide. While the US and Europe account for the bulk of those sales and thus the bulk of retail demand for the machine, Sony is still releasing PS4 in new territories on schedule. Supply constraints did not affect PS4's Japanese release in February.
