Midtown seems to be actively seeking tenants with a newish commercial listing for its retail spaces:

Given the size of the project, I'm not surprised it's taken them a few months to finalize permits and construction financing.
Thompson's Point is way, way behind its approved phasing schedule and seems mostly focused on being an outdoor concert venue for now, but they have fixed up one of the old brick buildings. One of the project's original partners recently cashed out and is now Portland's new city manager. So evidently, managing bureaucrats in City Hall offers more career excitement than Thompson's Point would have – not a great sign.
I ride my bike down there every now and then, and it's going to be a challenging site, a dead-end road cut off from the city by the Libbytown freeway ramps. It's not a walkable neighborhood by a long shot and there's not much reason to drive down there either.
