We know that there are two different apps, I initially thought that the Technical Preview for Windows 10 (phones) was replacing the older Developer Preview program. A recent article on here indicated that the technical preview will be much more Beta than the developer preview. Will there be a developer preview version of Windows 10 or is that program terminated completely?

That's a question we're all wondering about, just have to wait and see.

The Developer Preview was a way to access the complete, final update before the public.

The Technical Preview is a way to access the unfinished, still-needing-work software before the public.
My thinking is that the Insider program will eclipse the Developer Preview when we get close to the public launch, since it'll be more finished.

MS is just letting us average joes get in on the action much earlier in development.

I see the dev preview going away with their integration with the One store thing. as per having a slow and a fast build on phones, slow being near final builds and fast being needing testing. heck even though there may be high, medium and slow. IDK :)
