Irwindale Ca.Track closeing??

I read there may be an official announcement today regarding the future of the current Irwindale track. This hits my club, Inland Mopars, hard because we had confirmed approval from the Speedway to hold our annual all-Mopar car show on the Speedway property in May. We had some special incentives to show participants that would have made it a great event.
We started hearing rumblings about possible track closure a little over a month ago and pretty much confirmed it a couple of weeks ago.
I read on another forum that some demolition work has already started, but that hasn't been confirmed.
There may also be some noise issues with dragstrip at Fontana. My club is working a NMCA event there in April. I'll update with more information as soon as available.
