This also seems quite similar to repl.it, which I've been enjoying a lot recently.
I wonder if they'll support plugins and importing other VS Code settings to the online editor.

This is a minor variation of the existing Visual Studio Online (now renamed Visual Studio Codespace) product.
The core of it is running an automatically created azure hosted docker container. It automatically checks out your repository. It actually runs the whole VS Code backend on the remote machine, with the the user interface being provided by the "local" VS Code instance (web or desktop).
I'm going to bet this will end up with identical pricing to the existing product, at least if you don't pay for any github products. If you do, there might be some discount or included running time with those products.
The only part that sounds new here is the editor integration into the GitHub site.
