Windows Phone Developer Tools RTW -Final?

Is the "Windows Phone Developer Tools RTW" a final version?

RTW? Release to Web? Does this mean that it is a non final release or does it mean that it is only being released to the web?

I am thinking that this is a pre-release version.

The "R" in RTW stands for "Release", so no, this is not a pre-release. It is a full release, just to theg web. RTM wouldn't make sense, as they're not shipping the SDKs, etc to manufacturers, but instead to the development community.
