Nothing has changed as far as I know, but I would like to point out that the original targetted opening date was September 2014, and as soon as the preceding summer rolled around they pushed the targetted opening date to September 2016. This can be found on Bill Chavez's LinkedIn profile (I was creepn')-
"Imagine a multi-use, multi-impact, 365-day-a-year facility fronting Washington Street providing space for academics, athletics, student services and retail opportunities. The Gateway Project will enhance Eastern Washington University, creating a university living space that supports campus life, recruiting, retention and enhanced community access, while brining the existing football stadium to a level consistent with NCAA peers.
350,000 sf total area
20,000 sf street level retail
40,000 sf commercial office
12,000 seats (+10,000 delta)
Club area lounge and heated exterior seating
Premium seating with multiple tiers (loge, cabana and executive suites)
Football operations and performance center
Student-athlete academic success center
$54M estimated construction cost
Target opening date of September 2016"
My point is, that is only a little over a year away. If they planned to break ground within that year, I believe they would have announced something by now. In his recent podcasts, Chavez has stated that his team is now looking at other options regarding smaller projects to the stadium, incrementally.
