Thanks for the information - this does clear up a lot of confusion.
The only thing I'm left wondering is whether 1.2 will include any additional features besides 4 support. There are two features I've been looking forward to for a while now. One is the often requested ability to somehow import / export components between projects. If I recall correctly, it has been stated in the past that this would be in the 1.x line and I was wondering if this is still the case. The other is the fix for the defect where saving read-only files silently fails. This doesn't play nicely at all with my source control system.
Feedback on these items would be great, though I can understand the need not to release all your roadmap information.
