The long-awaited Steam Controller could be confusing your hands as soon as October or November, according to rumours emerging from this weekend's PAX East. The controller's release could also indicate that that Steam Machines will follow by the end of the year.
The release window comes from a "trusted hardware source" speaking to PC Gamer. The controller uses haptic feedback to bring traditional PC control schemes into a living room environment. It's been through several prototype iterations, but if this release window is true it must be nearing some kind of completion.
The source suggested that this means we could be seeing Steam Machines released shortly afterwards, perhaps in time for Christmas. The source also said that Steam expects "about 500" games to be natively playable on SteamOS by the end of the year. That's a significant increase from the current count of 382.
Hopefully we'll have confirmation of release dates soon.
