A source for PC Gamer has stated that Valve's highly anticipated Steam Controllers should be hitting the shelves in October or November.
The controllers, which received an updated prototype back in March adding a pair of four-button diamonds, have received attention mostly for their haptic trackpads, which have been designed to mimic the precision of a computer mouse as closely as possible. The controllers have also been designed for "user hackability", with Valve hoping to tap into the same creative potential found in its Steam Workshop.
PC Gamer's source also indicated that a finalised prototype of the steam controller was the last major obstacle to the release of Valve's Steam Machines, a console that will allow players to bring their Steam games onto a tv, bridging the gap between PC and console gaming. According to this source, players may also see Steam Machines hitting shelves at the end of this year.
