Opera has been being flamed to death in their own site since they posted the new browser preview. It is unlike anything I have ever witnessed in 35 years of tech work. Over 1500 posts with easily 90% negative.
They put out a new post yesterday:
You don't need to worry about Opera becoming a clone of something, or that you will be forced to stop using 12.x before you think we're ready. Our mission didn't change - we're going to bring you the best Internet experience. We are on the way to build the best browser out there. A browser that is not tied to the particular version number but is a continuously work in progress. Seeing your engagement I think we can count on your help and feedback.
So if something is not in Opera 15 stable - don't worry, Opera Next 16 will be released roughly same time as Opera 15 stable. And the time span between the two will be shorter than ever.
