Wow, that was a long post to support one simple point ;-)

And the plan is as follows:

Finish v2.1

release AVCHD first, as that will have the shortest rendering, authoring, uploading and downloading times.

render the larger BD video stream - author a simple BD with simple menu, lossless audio and only the some simple extras.

start working on ESB.

Keep working on extras throughout.

Release a bonus BD for the whole trilogy when it's all done.

So, no mkv ? :-) And I agree with the rest
