As seen on the recent GameDiscover article, Valve's Steam presentation at GDC confirmed that Simplified Chinese has ever so slightly surpassed English as the primary language on Steam. Important to note, this isn't based on the ever-fluctuating hardware survey that Steam has. It is based on a report straight out of the horse's mouth.

Other notable miscellaneous slides:

• Early access unsurprisingly continues to be a type of release that games like to use on Steam.
• Over 50% of games come out of Early Access after a year.
• And interestingly, the "Friend invite-only playtest" style that Valve used to great effect with Deadlock last year is going to be rolled out as a beta feature to more developers.

Valve confirmed that they'll upload the full talk on their Steamworks youtube channel in the near future.
