All you are going to have is a fancy API with nothing to plug into it.
* Web Cryptography API[1], edited by Mozilla and Google
* Media Source Extensions[2], edited by Google, Microsoft and Netflix
* Encrypted Media Extensions[3], edited by Google, Microsoft and Netflix
These are not pseudo standards pushed only by Microsoft. ChromeOS already supports two of these specs.

What's annoying is that you can run netflix on linux right now[1] via `netflix-desktop`, which combines `firefox`, `silverlight` and a modified copy of `wine` to access their site.
If they switch over to these new plugins and the plugins are IE-specific, we'll be locked out again.
