Steam Machines are still here, and they will be "front and center" at GDC this year.
The Valve representative said, "We're planning a very large presence at GDC with Steam Machines being front and center," after the company didn't appear at CES 2015 last week.
EA's Origin CEO Kevin Wasielewski was recently quoted saying the term "Steam Machine" was "pretty much dead". Instead he says "living room PC is now the new term."
A new design for the Steam Controller was leaked a few weeks ago, which we expect to see more of during GDC in March, along with Valve's "large" presence at the show.
