For a lack of other recent information:
I was invited on a tour of the Stadler Factory in Salt Lake City this last week. During the presentation before the tour we were shown a phased expansion plan for the site that involves adding a second assembly hall, a large carshell welding facility, and more finishing halls. The largest phase has been funded and should begin construction soon. The first phase would more than double the factory footprint while it will triple by the end of the project.
What stood out to me was a mention that there will be some capacity for stainless steel at this factory in the future to accommodate a stainless steel light-rail platform that they are currently bidding on at least two contracts in the US. It is guaranteed that any LD stock (Amtrak or VIA) will be stainless steel. Based on a vague answer from an employee on the subject, it is safe to assume that Stadler is also vying for VIA's LD order.
I also got to see Stadler's bid on the Amtrak intercity contract that Siemens ended up winning, they certainly had an interesting concept.
It'll probably be at least several more months before a preferred vendor is chosen. Though Stadler is a pretty long shot for LD stock, I am still anxiously awaiting news on the subject.
Here's the one picture I was allowed to take inside the factory:
