In the comments for my last post, nearly everyone was asking for VPC images to be provided along with Beta3 itself.
The good news: There will be VPC images made available for the Beta3 release.
The not-so-good news: They probably won't be available on the same day. It takes some time to get these set up properly and make sure they'll work as expected (if it was simple there wouldn't be a big push to publish them, right? :), and obviously it's not one of those things you can just throw more people at to get it done sooner. Look for one more post (probably not much more than a link) once the VPCs are made available. I'm assuming 'made available' implies 'on MSDN subscriber downloads', but I don't know the specifics just yet.
In the meantime, I better get back to that last handful of wacky resolve testcases...here's one: "Dependent rename - d renamed to c, c renamed to b, b renamed to a - get/resolve should be able to unravel in a single operation".
